Abstract
Description
[0001] This case is a divisional application. The original application was entitled "An equipment for building electromechanical installation". The original application was filed on September 12, 2023, and the original application number was 202311171776.5. Technical Field
[0002] This invention relates to the field of building electromechanical installation technology, and more particularly to a device for building electromechanical installation. Background Technology
[0003] Electromechanical installation refers to the process of installing, commissioning, and maintaining electromechanical equipment in buildings or industrial facilities. This equipment includes electrical equipment, ventilation and air conditioning equipment, water treatment equipment, piping systems, etc. Cable laying is a crucial step in electromechanical installation, as cables are frequently used to connect various electromechanical devices. Direct-buried cables are a method of cable laying in building electromechanical installation projects, specifically referring to burying cables directly underground for power or signal transmission. This is mainly used in building projects requiring power or communication, such as residential communities, commercial buildings, and industrial plants, where direct-buried cable laying may be necessary. This is to transmit power or signals to different equipment or points of application, such as lighting, air conditioning, security systems, and communication networks. Direct-buried cables can reduce space occupation and installation costs while providing better power and signal transmission performance.
[0004] When carrying out direct burial cable operations, the first step is to excavate the earthwork to create a burial channel as required. After excavation, to protect the cable from external forces and environmental factors, a protective material of a certain thickness, such as gravel or fine sand, needs to be laid on the bottom surface of the burial channel. Additionally, after the cable is laid, a layer of fine sand of a certain thickness also needs to be laid to protect the cable. Currently, fine sand laying is generally done manually, making it difficult to control the sand layer thickness. Especially in projects with strict requirements on sand layer thickness, repeated leveling is often necessary, which is time-consuming, labor-intensive, and inefficient. Therefore, this paper designs a device for building electromechanical installation. Summary of the Invention
[0005] The purpose of this invention is to provide a device for building electromechanical installation that is simple to operate and improves the efficiency of fine sand layer laying.
[0006] This invention is achieved through the following measures: An apparatus for building electromechanical installation, characterized in that it includes a support mechanism and a main body of equipment that moves by means of the support mechanism; The main body of the equipment includes a rectangular frame, the width of which matches the width of the burial channel. Specifically, the two long sides of the rectangular frame are flush with the two long walls of the burial channel. A pair of identical sand-blocking plates, Sand-blocking Plate 1 and Sand-blocking Plate 2, are installed inside the rectangular frame. Both Sand-blocking Plate 1 and Sand-blocking Plate 2 are parallel to and close to the wide sides of the rectangular frame. Both Sand-blocking Plate 1 and Sand-blocking Plate 2 have sand-draining holes. A rear side of the rectangular frame relative to the forward direction of the equipment body is provided with… The scraper is L-shaped with an arc-shaped inner side. The lower surface of the scraper is aligned with the lower edge of the sand-leaking hole and the lower side of the rectangular frame. The height of the lower surface of the scraper from the bottom of the burial channel is the required sand-laying thickness. During sand-laying, the main body of the equipment is first moved close to one end of the burial channel or the end face of a pre-laid fine sand layer (the end face of the fine sand layer is a slope due to the fluid properties of fine sand). Sand is then poured between the first and second sand-blocking plates within the rectangular frame. Fine sand is added until it exceeds the sand leakage hole. Additionally, the gap between the corresponding end of the buried channel or the end face of the pre-laid fine sand layer and the adjacent sand baffle plate one or sand baffle plate two needs to be filled with fine sand through the sand leakage hole until the fine sand is flush with the lower side of the sand leakage hole. This step is only used when laying the first section of fine sand layer using this equipment. Afterwards, the sand baffle plate two is pulled out. Since the thickness of sand baffle plate one and sand baffle plate two is small, the gap formed after pulling them out has a negligible impact on the overall thickness of the fine sand layer. Then, the rectangular frame is moved. When the rectangular frame moves, the first sand baffle on the front side does not move. The sand scraper moves with the main body of the equipment and scrapes off the excess fine sand that is higher than the lower side of the sand leakage hole. Then, the excess fine sand is pushed through the sand leakage hole on the first sand baffle in front and into the buried channel between the unfilled rectangular frames. When the sand scraper approaches the first sand baffle in front, a section of fine sand of a certain thickness is laid. Then, the second sand baffle on the rear side, which was pulled out earlier, is inserted into the front side of the rectangular frame to lay the next section of fine sand.
[0007] The invention also has the following specific features: A sliding groove is provided on both long sides of the rectangular frame along the length direction. A front sliding groove and a rear sliding groove are respectively provided at both ends of the sliding groove, which extend upward through the upper end of the long side. The front sliding groove is located closer to the front side away from the rear side, and the rear sliding groove is located closer to the rear side. Both sides of the sand baffle plate 1 and the sand baffle plate 2 are provided with sliders that cooperate with the front sliding groove and the rear sliding groove. The sand baffle plate 1 or the sand baffle plate 2 is inserted along the front sliding groove or the rear sliding groove, and then can slide along the sliding groove 1. An elastic limiting mechanism is provided in the first slide groove near the front slide groove. The elastic limiting mechanism includes a U-shaped groove in the first slide groove, and a U-shaped slider is provided in the U-shaped groove. The gap between the two sides of the U-shaped slider is greater than the width of the first sand baffle or the second sand baffle, that is, the first sand baffle or the second sand baffle can be locked between the two sides of the U-shaped slider. A pair of springs are provided between the bottom surface of the U-shaped groove and the U-shaped slider. One end of the spring is fixed to the bottom surface of the U-shaped groove, and the other end of the spring is fixed to the U-shaped slider. One side of the U-shaped slider is provided with an inclined surface, which corresponds to the front slide groove. When the first or second sand baffle is inserted into the front slide groove, the slider presses the U-shaped slider along the inclined surface. When the slider reaches the slide groove, the U-shaped slider is completely pressed into the U-shaped groove. When the first or second sand baffle slides along the slide groove toward the rear slide groove, that is, when the slider enters the gap between the two sides of the U-shaped slider, the U-shaped slider is reset under the action of the first spring, so that the first or second sand baffle is limited between the two sides of the U-shaped slider.
[0008] A clamping mechanism is provided on the front side of the rectangular frame. The clamping mechanism includes several springs II provided on the front side. The free ends of the springs II are provided with top blocks. The side of the top block away from the springs II is clamped against the sand baffle I or the sand baffle II between the two sides of the U-shaped slider. The top block is provided with a slope II. The function of the slope II is to facilitate the insertion of the sand baffle I or the sand baffle II into the front slide groove.
[0009] The main body of the equipment also includes a partitioning mechanism, which includes a pair of slides and a partition portion disposed between the pair of slides. A pair of grooves are respectively disposed on the upper side of the long side of the rectangular frame and extend through the rear side. The partition includes a partition plate. A vertical plate is disposed on one side of the partition plate. Slide plates are disposed on both sides of the vertical plate to cooperate with the grooves. A connecting rod is disposed between the free ends of the slide plates on both sides. After the slide plates on both sides are disposed in the grooves on the corresponding sides, a connecting rod is disposed between the connecting rod and the partition plate. The partition plate cooperates with the rectangular frame and slides along the lower surface of the scraper. At this time, the distance between the lower surface of the partition plate and the bottom surface of the buried channel is the thickness of the fine sand layer. This distance can be adjusted by adjusting the support mechanism to change the thickness of the fine sand layer. When the partition mechanism slides, it can separate excess fine sand on the partition plate. Then, the scraper pushes the excess fine sand to the un-laid area in the rectangular frame. The fine sand layer below the partition plate is the fine sand layer of the required thickness. Because fine sand has fluid properties, when there is a lot of excess fine sand, it is quite difficult to push it simply by the scraper. At the same time, due to the stickiness between the sand layers, the scraper will also have an adverse effect on the required fine sand layer during the pushing process. The separation mechanism can solve the above problems.
[0010] The main body of the equipment also includes a plate-shifting mechanism. The plate-shifting mechanism includes a vertical plate (I) mounted on the partition plate, positioned close to the vertical plate. A through groove (I) is provided on the vertical plate (I). An electric telescopic rod (I) is mounted on the lower side of the through groove (I). A sliding plate (II) is mounted on the free end of the electric telescopic rod (I). Correspondingly, sliding grooves (III) are provided on both sides of the through groove (I). The sliding plate (II) is positioned within the sliding grooves (III) on both sides. A horizontal electric telescopic rod (II) is mounted on the sliding plate (II), with its free end extending out of the through groove (I). A fixing block is provided at the rear, and a cylindrical electromagnet is provided on the lower side of the fixing block. Correspondingly, a cylindrical rod is provided on the upper side of both the first and second sand baffles. A circular groove is provided on the upper end face of the cylindrical rod to cooperate with the electromagnet. A metal block is provided on the bottom surface of the circular groove to cooperate with the electromagnet. The corresponding sand baffle or sand baffle can be pulled up or inserted into the front slide groove by the plate moving mechanism. The attraction of the first or sand baffle can be controlled by the circuit switching of the electromagnet.
[0011] The main body of the equipment also includes an interlocking mechanism, which includes a front locking part, a rear locking part, and a driving part; The front locking part includes a pair of upright plates 2, which are symmetrically arranged on the upper side of the long side of the rectangular frame and close to the front side. Each upright plate 2 has a through groove 2, and each side of the through groove 2 has a sliding groove 4. A front locking pin is slidably arranged between the two through grooves 2. The front locking pin includes a crossbar 1, and each side of the crossbar 1 has a sliding plate 3 that cooperates with the sliding groove 4. Each sliding plate 3 is arranged between the corresponding two sliding grooves 4. The lower side of the sliding plate 3 has a thin insert plate 1 that slides against the outer side of the long side. The lower end of the thin insert plate 1 is a pointed structure. The rear locking part includes a pair of upright plates three. The pair of upright plates three are symmetrically arranged on the inner side of the two sliding plates one on both sides and close to the upright plates three via a bracket plate one. Each of the two upright plates three is provided with a through groove three. Each of the two sides of the through groove three is provided with a sliding groove five. A rear locking pin is slidably arranged between the two through grooves three. The rear locking pin includes a crossbar two. Each side of the crossbar two is provided with a sliding plate four that cooperates with the sliding groove five. Each of the two sliding plates four is arranged between the corresponding two sliding grooves five. A thin insert plate two is provided on the lower side of the sliding plate four. The lower end of the thin insert plate two slides through the partition plate and is set as a pointed structure.
[0012] A rack 1 connected to the drive unit is provided on one side of the slide plate 3, and a rack 2 connected to the drive unit is provided on the slide plate 4 on the same side as the rack.
[0013] The drive unit includes a rotating shaft, which is mounted on the long side of the rack via a bracket plate. An intermediate gear is provided on the outer side of the rotating shaft, and a gear that meshes with the rack is provided at one end of the rotating shaft. A circular groove is provided on the end face of the other end of the rotating shaft, and an internal spline is provided on the inner wall of the groove. A rotating shaft 2 is provided on the vertical plate 3 on the same side as the rack 2 via a bracket plate 3. One end of the rotating shaft 2 is provided with a gear 2 that meshes with the rack 2, and the other end of the rotating shaft 2 is provided with an external spline that mates with the internal spline. The rotating shaft 2 is disposed in the groove 2 through the engagement of the internal spline and the external spline. The rotating shaft 2 is sleeved in the groove 2 and slides along the groove 2, realizing the extension and retraction between the rotating shaft 1 and the rotating shaft 2. At the same time, due to the engagement of the internal spline and the external spline, the rotating shaft 2 rotates with the rotating shaft 1. A motor is mounted on the second support plate. The output end of the motor is equipped with a drive gear that meshes with the intermediate gear. Rack 1 and rack 2 are respectively located on both sides of shaft 1 or shaft 2. The motor drives the drive gear to rotate, which in turn drives the intermediate gear to rotate, which in turn drives shaft 1 to rotate, which in turn drives shaft 2 to rotate, which in turn drives gear 1 and gear 2 to rotate, which in turn causes the corresponding front locking pin and rear locking pin to slide up and down. Since rack 1 and rack 2 are respectively located on both sides of shaft 1 or shaft 2, when the front locking pin slides up, the rear locking pin slides down, and vice versa.
[0014] The support mechanism consists of a pair of rails respectively set on the two side walls in the width direction of the buried channel, and the main body of the equipment is slidably set between the two rails.
[0015] The support mechanism consists of several roller mechanisms disposed on the lower sides of both sides of the rectangular frame. Each roller mechanism includes a lower side plate, which is disposed on the upper side of the rectangular frame and has rollers disposed on the lower side. The lower side plate is a telescopic plate.
[0016] Working principle: During construction, the equipment is placed in the buried channel. The distance between the partition plate and the bottom of the buried channel is adjusted according to the required thickness of the fine sand layer. If the support mechanism is the track, it can be adjusted by adjusting the installation height of the track. If the support mechanism is a roller mechanism, the roller mechanism can be set in the telescopic structure for easy adjustment of the distance. In the initial state, a layer of fine sand of the required thickness is laid at the starting end of the burial channel. Then, the main body of the equipment is moved to the point where the laid fine sand layer is lifted, and the separating mechanism is slid to the outermost side away from the rectangular frame, so that the separating mechanism is on the upper surface of the laid fine sand layer. Next, sand-blocking plate one and sand-blocking plate two are inserted into the front and rear sliding grooves respectively. At this time, sand-blocking plate one inserted into the front sliding groove is between the two sides of the U-shaped slider, and sand-blocking plate two in the rear sliding groove is close to the end face of the pre-laid fine sand layer. Additionally, the front locking pin is inserted into the bottom surface of the burial channel. The rectangular frame is locked, and then fine sand is filled between the first and second sand baffles within the rectangular frame until the fine sand exceeds the sand leakage hole. In addition, the gap between the end face of the pre-laid fine sand layer and the second sand baffle needs to be filled with fine sand through the sand leakage hole until the fine sand is flush with the lower side of the sand leakage hole. Then, the first and second electric telescopic rods are activated to pull out the second sand baffle on the rear side and insert it forward into the front sliding groove. At this time, the U-shaped slider is completely squeezed into the U-shaped groove, releasing the lock on the first sand baffle, while the top block presses against the side of the second sand baffle. Then, the electric telescopic rod two retracts. Since the free end of the electric telescopic rod two is fixed to the sand-blocking plate two through the cooperation of the electromagnet and the metal block, and the sand-blocking plate two is limited by the rectangular frame, when the electric telescopic rod two retracts, it will drive the partition plate to slide forward, and excess fine sand will be separated on the partition plate. Then, through the interlocking mechanism, the front locking pin moves upward to release the lock on the rectangular frame, while the rear locking pin moves downward to insert into the bottom surface of the burial channel to lock the partition mechanism. Then, the electric telescopic rod two extends. At this time, the electric telescopic rod two will push the rectangular frame forward. After the movement begins, since the sand-blocking plate one is released from its lock with the rectangular frame, one part of the sand-blocking plate remains stationary in its original position, moving along the rectangular frame as it moves. The slide chute 1 slides (because the fine sand cross-section after laying has a certain adhesion to the sand baffle 1, it can remain unmoved when the rectangular frame moves, and can only slide along the slide chute 1. As an embodiment, an external force can be applied to the sand baffle 1 to further keep the sand baffle 1 stationary in its original position). The excess fine sand on the partition plate is pushed to the unlaid area in the rectangular frame by the pushing of the sand scraper. The fine sand layer under the partition plate is the fine sand layer of the required thickness. When the sand baffle 1 reaches the position of the rear slide chute, the electric telescopic rod 2 stops and retracts after disengaging from the sand baffle 2. Then, the rectangular frame is locked by the interlocking mechanism, and then the next section of fine sand layer laying operation is carried out until the entire buried channel is laid.
[0017] The beneficial effects of this invention are: the equipment has a simple structure and is easy to use. In particular, it can improve the efficiency of fine sand layer laying and save manpower, especially in projects where the thickness of the fine sand layer is required. Attached Figure Description

Detailed Implementation
[0032] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0033] Example 1 See Figure 1 , Figure 3 and Figure 10 An apparatus for building electromechanical installation includes a support mechanism and a main body 2 of equipment that moves based on the support mechanism; The main body 2 of the equipment includes a rectangular frame 18. The width of the rectangular frame 18 matches the width of the burial channel, meaning that the two long sides of the rectangular frame 18 along the length direction are tightly attached to the two side walls of the burial channel along the length direction. A pair of identical sand-blocking plates 19 and 16 are installed inside the rectangular frame 18. Both sand-blocking plates 19 and 16 are parallel to the wide sides of the rectangular frame 18 along the width direction and are close to the two wide sides respectively. Both sand-blocking plates 19 and 16 are provided with sand-leaking holes 40. The rear side of the rectangular frame 18 relative to the forward direction of the main body 2... A scraper plate 45 is provided on the surface. The scraper plate 45 is L-shaped with an arc-shaped inner side. The lower surface of the scraper plate 45 is aligned with the lower side of the sand leakage hole 40 and the lower side of the rectangular frame 18. The height between the lower surface of the scraper plate and the bottom of the buried channel is the required sand thickness. During the sand application operation, the main body 2 of the mobile device is first moved close to one end of the buried channel or the end face of a pre-laid fine sand layer (because fine sand has certain fluid characteristics, the end face of the fine sand layer here is a slope), and the sand is applied to the sand baffle plate 19 and sand baffle plate 16 inside the rectangular frame 18. Fill the gaps with fine sand until it exceeds the sand leakage hole 40. Additionally, the gap between the corresponding end of the buried channel or the end face of the pre-laid fine sand layer and the adjacent sand baffle 19 or sand baffle 216 needs to be filled with fine sand through the sand leakage hole 40 until the fine sand is flush with the lower side of the sand leakage hole 40. This step is only used when laying the first section of fine sand layer using this equipment. Afterwards, pull out the sand baffle 216. Since the thickness of sand baffle 19 and sand baffle 216 is relatively small, the gap formed after pulling them out has a negligible impact on the overall thickness of the fine sand layer. Then move the rectangular frame 18. Note that when the rectangular frame 18 moves, the front sand baffle 19 does not move. The sand scraper 45 moves with the main body 2 and scrapes off the excess fine sand that is higher than the lower side of the sand leakage hole 40. Then, the excess fine sand is pushed through the sand leakage hole 40 on the front sand baffle 19 into the buried channel between the unfilled rectangular frames 18. When the sand scraper 45 approaches the front sand baffle 19, a section of fine sand of a certain thickness is laid. Then, the rear sand baffle 16 that was pulled out is inserted into the front side of the rectangular frame 18 to lay the next section of fine sand.
[0034] Example 2 See Figure 1 , Figures 3-13 An apparatus for building electromechanical installation includes a support mechanism and a main body 2 of equipment that moves based on the support mechanism; The main body 2 of the equipment includes a rectangular frame 18. The width of the rectangular frame 18 matches the width of the buried channel. That is, the two long sides of the rectangular frame 18 along the length direction are close to the two side walls of the buried channel along the length direction. A pair of sand baffles 19 and 16 with the same structure are provided inside the rectangular frame 18. Both sand baffles 19 and 16 are parallel to the wide side of the rectangular frame 18 along the width direction and are close to the two wide side sides respectively. Both sand baffles 19 and 16 are provided with sand leakage holes 40. A sand scraper 45 is provided on the rear side of the rectangular frame 18 relative to the forward direction of the main body 2. The sand scraper 45 is L-shaped and the inner side is set with an arc structure. The lower surface of the sand scraper 45 is aligned with the lower side edge of the sand leakage hole 40 and the lower side of the rectangular frame 18.
[0035] A sliding groove 6 is provided on both long sides of the rectangular frame 18 along the length direction. A front sliding groove 33 and a rear sliding groove 34 are respectively provided at both ends of the sliding groove 6, which extend upward through the upper end of the long side. The front sliding groove 33 is located closer to the front side away from the rear side, and the rear sliding groove 34 is located closer to the rear side. A slider 41 that cooperates with the front sliding groove 33 and the rear sliding groove 34 is provided on both sides of the sand baffle 19 and the sand baffle 2 16. The sand baffle 19 or the sand baffle 2 16 is inserted along the front sliding groove 33 or the rear sliding groove 34, and then can slide along the sliding groove 6. An elastic limiting mechanism is provided in the slide groove 6 near the front slide groove 33. The elastic limiting mechanism includes a U-shaped groove 37 in the slide groove 6 and a U-shaped slider 36 in the U-shaped groove 37. The gap between the two sides of the U-shaped slider 36 is greater than the width of the sand baffle 19 or the sand baffle 2 16. That is, the sand baffle 19 or the sand baffle 2 16 can be locked between the two sides of the U-shaped slider 36. A pair of springs 38 are provided between the bottom surface of the U-shaped groove 37 and the U-shaped slider 36. One end of the springs 38 is fixed to the bottom surface of the U-shaped groove 37, and the other end of the springs 38 is fixed to the U-shaped slider 36. One side of the U-shaped slider 36, corresponding to the front slide groove 33, is provided with an inclined surface 35. When the sand baffle 19 or sand baffle 2 16 is inserted into the front slide groove 33, the slider 41 presses the U-shaped slider 36 along the inclined surface 35. When the slider 41 reaches the slide groove 6, the U-shaped slider 36 is completely pressed into the U-shaped groove 37. When the sand baffle 19 or sand baffle 2 16 slides along the slide groove 6 toward the rear slide groove 34, that is, when the slider 41 enters the gap between the two sides of the U-shaped slider 36, the U-shaped slider 36 is reset under the action of the spring 38, so that the sand baffle 19 or sand baffle 2 16 is limited between the two sides of the U-shaped slider 36.
[0036] A clamping mechanism is provided on the front side of the rectangular frame 18. The clamping mechanism includes several springs 32 on the front side. The free ends of the springs 32 are provided with top blocks 30. The side of the top block 30 away from the springs 32 is clamped to the sand baffle 19 or sand baffle 16 between the two sides of the U-shaped slider 36. The top block 30 is provided with a slope 31. The function of the slope 31 is to facilitate the insertion of the sand baffle 19 or sand baffle 16 into the front slide groove 33.
[0037] The main body 2 of the equipment also includes a separating mechanism, which includes a pair of slides 5 and a separating part disposed between the pair of slides 5; A pair of slids 2 5 are respectively set on the upper side of the long side of the rectangular frame 18 and extend through the rear side. The partition includes a partition plate 14. A vertical plate 12 is set on one side of the partition plate 14. A sliding plate 13 that cooperates with the slids 2 5 is set on both sides of the vertical plate 12. A connecting rod 46 is set between the free ends of the sliding plates 13 on both sides. After the sliding plates 13 on both sides are set in the slids 2 5 on the corresponding side, a connecting rod 47 is set between the connecting rod 46 and the partition plate 14. The partition plate 14 cooperates with the rectangular frame 18 and slides along the lower surface of the scraper 45. At this time, the distance between the lower surface of the partition plate 14 and the bottom surface of the buried channel is the thickness of the fine sand layer. This distance can be adjusted by adjusting the support mechanism to change the thickness of the fine sand layer. When the partition mechanism slides, the excess fine sand can be separated on the partition plate 14. Then, the excess fine sand is pushed to the unlaid area in the front rectangular frame 18 by the pushing of the scraper 45. The fine sand layer under the partition plate 14 is the fine sand layer of the required thickness. Because fine sand has fluid properties, when there is a lot of excess fine sand, it is difficult to push it simply by scraping the sand with the scraper 45. At the same time, due to the stickiness between the sand layers, the scraper 45 will also have an adverse effect on the required fine sand layer during the pushing process. The separation mechanism can solve the above problems.
[0038] The main body 2 of the equipment also includes a plate-shifting mechanism, which includes a vertical plate 9 set on the partition plate 14. The vertical plate 9 is positioned close to the vertical plate 12. A through groove 1 is provided on the vertical plate 9. An electric telescopic rod 10 is provided on the lower side of the through groove 1. A sliding plate 2 is provided at the free end of the electric telescopic rod 10. Correspondingly, sliding grooves 3 are provided on both sides of the through groove 1. The sliding plate 2 is set in the sliding grooves 3 on both sides.

A thin insert plate 2 44 is provided on the lower side of the slide plate 43. The lower end of the thin insert plate 2 44 slides through the partition plate 14 and is set as a pointed structure.
[0040] A rack 42 connected to the drive unit is provided on one side of the slide plate 3 21, and a rack 28 connected to the drive unit is provided on the slide plate 43 on the same side as the rack 42.
[0041] The drive unit includes a rotating shaft 17, which is mounted on the long side of the rack 42 via a bracket plate 2. An intermediate gear 26 is provided on the outer side of the rotating shaft 17. A gear 22 that meshes with the rack 42 is provided at one end of the rotating shaft 17. A circular groove 2 is provided on the end face of the other end of the rotating shaft 17. An internal spline is provided on the inner wall of the groove 2. On the same side as rack 28, on vertical plate 3 27, a rotating shaft 2 15 is provided via bracket plate 3. One end of rotating shaft 2 15 is provided with gear 2 29 that meshes with rack 28, and the other end of rotating shaft 2 15 is provided with external spline that mates with internal spline. Rotating shaft 2 15 is set in groove 2 through the engagement of internal spline and external spline. Rotating shaft 2 29 is sleeved in groove 2 and slides along groove 2, realizing the extension and retraction between rotating shaft 1 17 and rotating shaft 2 29. At the same time, due to the engagement of internal spline and external spline, rotating shaft 2 29 rotates with rotating shaft 1 17. A motor 24 is installed on the second bracket plate. The output end of the motor 24 is equipped with a drive gear 25 that meshes with the intermediate gear 26. Rack 1 42 and rack 28 are respectively installed on both sides of shaft 1 17 or shaft 2 15. The motor 24 drives the drive gear 25 to rotate, which in turn drives the intermediate gear 26 to rotate, which in turn drives shaft 1 17 to rotate, which in turn drives shaft 2 15 to rotate, which in turn drives gear 1 22 and gear 2 29 to rotate, which in turn drives the corresponding front locking pin 4 and rear locking pin 11 to slide up and down. Since rack 1 42 and rack 2 28 are respectively installed on both sides of shaft 1 17 or shaft 2 15, when the front locking pin 4 slides up, the rear locking pin 11 slides down, and vice versa.
[0042] The support mechanism consists of a pair of rails 1 respectively set on the side walls on both sides in the width direction of the buried channel, and the main body of the equipment 2 is slidably set between the two rails 1.
[0043] Working principle: During construction, the equipment is placed in the buried channel. The distance between the partition plate 14 and the bottom of the buried channel is adjusted according to the required thickness of the fine sand layer. If the support mechanism is the track 1, it can be achieved by adjusting the installation height of the track 1. If the support mechanism is the roller mechanism 3, the roller mechanism 3 can be set in the telescopic structure for easy adjustment of the distance. In the initial state, a layer of fine sand meeting the required thickness is laid at the starting end of the burial channel. Then, the main body 2 is moved to the point where the laid fine sand layer is lifted, and the separating mechanism is slid to the outermost side away from the rectangular frame 18, so that the separating mechanism is positioned on the upper surface of the laid fine sand layer. Next, sand baffle plate 19 and sand baffle plate 16 are inserted into the front slide groove 33 and rear slide groove 34 respectively. At this time, sand baffle plate 19 inserted into the front slide groove 33 is positioned between the two sides of the U-shaped slider 36, and sand baffle plate 16 in the rear slide groove 34 is close to the end face of the pre-laid fine sand layer. Additionally, the front locking pin 4 is inserted into the bottom surface of the burial channel. The rectangular frame 18 is locked. Then, fine sand is filled between the sand baffle 19 and sand baffle 2 16 inside the rectangular frame 18 until the fine sand exceeds the sand leakage hole 40. In addition, the gap between the end face of the pre-laid fine sand layer and the sand baffle 2 16 needs to be filled with fine sand through the sand leakage hole 40 until the fine sand is flush with the lower side of the sand leakage hole 40. Then, the electric telescopic rod 10 and the electric telescopic rod 28 are activated to pull out the sand baffle 2 16 on the rear side and insert it forward into the front slide groove 33. At this time, the U-shaped slider 36 is completely squeezed into the U-shaped groove 37, releasing the lock on the sand baffle 19. At the same time, the top block 30 is pressed against the side of the sand baffle 2 16. Then, the electric telescopic rod 28 retracts. Since the free end of the electric telescopic rod 28 is fixed to the sand baffle 216 through the cooperation of the electromagnet 7 and the metal block, and the sand baffle 216 is limited by the rectangular frame 18, when the electric telescopic rod 28 retracts, it will drive the partition plate 14 to slide forward, and the excess fine sand will be separated on the partition plate 14. Then, through the interlocking mechanism, the front locking pin 4 moves upward to release the lock on the rectangular frame 18, and then the locking pin 11 moves downward to insert into the bottom surface of the buried channel to lock the partition mechanism. Then, the electric telescopic rod 28 extends. At this time, the electric telescopic rod 28 will push the rectangular frame 18 forward. After the movement begins, since the sand baffle 19 is released from the lock between it and the rectangular frame 18, the sand baffle 19 remains in its original position and slides along the slide groove 6 as the rectangular frame 18 moves. (Because the fine sand cross-section after laying has a certain adhesion to the sand baffle plate 19, it can remain unmoved when the rectangular frame 18 moves, and can only slide along the slide groove 6. As an example, the sand baffle plate 19 can be kept in its original position by applying external force to it.) The excess fine sand on the partition plate 14 is pushed to the unlaid area in the front rectangular frame 18 by the pushing of the sand scraper 45. The fine sand layer under the partition plate 14 is the fine sand layer of the required thickness. When the sand baffle plate 19 reaches the position of the rear slide groove 34, the electric telescopic rod 28 is stopped and the electric telescopic rod 28 is disengaged from the sand baffle plate 26 and retracted. Then the rectangular frame 18 is locked by the interlocking mechanism, and then the next section of fine sand layer laying operation is carried out until the entire buried channel is laid.
[0044] Example 3 See Figure 2-13An apparatus for building electromechanical installation includes a support mechanism and a main body 2 of equipment that moves based on the support mechanism; The main body 2 of the equipment includes a rectangular frame 18. The width of the rectangular frame 18 matches the width of the buried channel. That is, the two long sides of the rectangular frame 18 along the length direction are close to the two side walls of the buried channel along the length direction. A pair of sand baffles 19 and 16 with the same structure are provided inside the rectangular frame 18. Both sand baffles 19 and 16 are parallel to the wide side of the rectangular frame 18 along the width direction and are close to the two wide side sides respectively. Both sand baffles 19 and 16 are provided with sand leakage holes 40. A sand scraper 45 is provided on the rear side of the rectangular frame 18 relative to the forward direction of the main body 2. The sand scraper 45 is L-shaped and the inner side is set with an arc structure. The lower surface of the sand scraper 45 is aligned with the lower side edge of the sand leakage hole 40 and the lower side of the rectangular frame 18.
[0045] A sliding groove 6 is provided on both long sides of the rectangular frame 18 along the length direction. A front sliding groove 33 and a rear sliding groove 34 are respectively provided at both ends of the sliding groove 6, which extend upward through the upper end of the long side. The front sliding groove 33 is located closer to the front side away from the rear side, and the rear sliding groove 34 is located closer to the rear side. A slider 41 that cooperates with the front sliding groove 33 and the rear sliding groove 34 is provided on both sides of the sand baffle 19 and the sand baffle 2 16. The sand baffle 19 or the sand baffle 2 16 is inserted along the front sliding groove 33 or the rear sliding groove 34, and then can slide along the sliding groove 6. An elastic limiting mechanism is provided in the slide groove 6 near the front slide groove 33. The elastic limiting mechanism includes a U-shaped groove 37 in the slide groove 6 and a U-shaped slider 36 in the U-shaped groove 37. The gap between the two sides of the U-shaped slider 36 is greater than the width of the sand baffle 19 or the sand baffle 2 16. That is, the sand baffle 19 or the sand baffle 2 16 can be locked between the two sides of the U-shaped slider 36. A pair of springs 38 are provided between the bottom surface of the U-shaped groove 37 and the U-shaped slider 36. One end of the springs 38 is fixed to the bottom surface of the U-shaped groove 37, and the other end of the springs 38 is fixed to the U-shaped slider 36. One side of the U-shaped slider 36, corresponding to the front slide groove 33, is provided with an inclined surface 35. When the sand baffle 19 or sand baffle 2 16 is inserted into the front slide groove 33, the slider 41 presses the U-shaped slider 36 along the inclined surface 35. When the slider 41 reaches the slide groove 6, the U-shaped slider 36 is completely pressed into the U-shaped groove 37. When the sand baffle 19 or sand baffle 2 16 slides along the slide groove 6 toward the rear slide groove 34, that is, when the slider 41 enters the gap between the two sides of the U-shaped slider 36, the U-shaped slider 36 is reset under the action of the spring 38, so that the sand baffle 19 or sand baffle 2 16 is limited between the two sides of the U-shaped slider 36.
[0046] A clamping mechanism is provided on the front side of the rectangular frame 18. The clamping mechanism includes several springs 32 on the front side. The free ends of the springs 32 are provided with top blocks 30. The side of the top block 30 away from the springs 32 is clamped to the sand baffle 19 or sand baffle 16 between the two sides of the U-shaped slider 36. The top block 30 is provided with a slope 31. The function of the slope 31 is to facilitate the insertion of the sand baffle 19 or sand baffle 16 into the front slide groove 33.
[0047] The main body 2 of the equipment also includes a separating mechanism, which includes a pair of slides 5 and a separating part disposed between the pair of slides 5; A pair of slids 2 5 are respectively set on the upper side of the long side of the rectangular frame 18 and extend through the rear side. The partition includes a partition plate 14. A vertical plate 12 is set on one side of the partition plate 14. A sliding plate 13 that cooperates with the slids 2 5 is set on both sides of the vertical plate 12. A connecting rod 46 is set between the free ends of the sliding plates 13 on both sides. After the sliding plates 13 on both sides are set in the slids 2 5 on the corresponding side, a connecting rod 47 is set between the connecting rod 46 and the partition plate 14. The partition plate 14 cooperates with the rectangular frame 18 and slides along the lower surface of the scraper 45. At this time, the distance between the lower surface of the partition plate 14 and the bottom surface of the buried channel is the thickness of the fine sand layer. This distance can be adjusted by adjusting the support mechanism to change the thickness of the fine sand layer. When the partition mechanism slides, the excess fine sand can be separated on the partition plate 14. Then, the excess fine sand is pushed to the unlaid area in the front rectangular frame 18 by the pushing of the scraper 45. The fine sand layer under the partition plate 14 is the fine sand layer of the required thickness. Because fine sand has fluid properties, when there is a lot of excess fine sand, it is difficult to push it simply by scraping the sand with the scraper 45. At the same time, due to the stickiness between the sand layers, the scraper 45 will also have an adverse effect on the required fine sand layer during the pushing process. The separation mechanism can solve the above problems.
[0048] The main body 2 of the equipment also includes a plate-shifting mechanism, which includes a vertical plate 9 set on the partition plate 14. The vertical plate 9 is positioned close to the vertical plate 12. A through groove 1 is provided on the vertical plate 9.

A fixed block is provided with a cylindrical electromagnet 7 on its lower side. The upper sides of the corresponding sand baffle 19 and sand baffle 2 16 are provided with cylindrical rods 39. The upper end face of the cylindrical rod 39 is provided with a circular groove 1 that cooperates with the electromagnet 7. The bottom surface of the circular groove 1 is provided with a metal block that cooperates with the electromagnet 7. The corresponding sand baffle 19 or sand baffle 2 16 can be pulled up or inserted into the front slide groove 33 by the plate moving mechanism. The attraction of sand baffle 19 or sand baffle 2 16 can be controlled by the circuit switching of the electromagnet 7.
[0049] The main body 2 of the equipment also includes an interlocking mechanism, which includes a front locking part, a rear locking part and a driving part; The front locking part includes a pair of upright plates 20.

[0050] A rack 42 connected to the drive unit is provided on one side of the slide plate 3 21, and a rack 28 connected to the drive unit is provided on the slide plate 43 on the same side as the rack 42.
[0051] The drive unit includes a rotating shaft 17, which is mounted on the long side of the rack 42 via a bracket plate 2. An intermediate gear 26 is provided on the outer side of the rotating shaft 17. A gear 22 that meshes with the rack 42 is provided at one end of the rotating shaft 17. A circular groove 2 is provided on the end face of the other end of the rotating shaft 17. An internal spline is provided on the inner wall of the groove 2.

One end of rotating shaft 2 15 is provided with gear 2 29 that meshes with rack 28, and the other end of rotating shaft 2 15 is provided with external spline that mates with internal spline. Rotating shaft 2 15 is set in groove 2 through the engagement of internal spline and external spline. Rotating shaft 2 29 is sleeved in groove 2 and slides along groove 2, realizing the extension and retraction between rotating shaft 1 17 and rotating shaft 2 29. At the same time, due to the engagement of internal spline and external spline, rotating shaft 2 29 rotates with rotating shaft 1 17. A motor 24 is installed on the second bracket plate. The output end of the motor 24 is equipped with a drive gear 25 that meshes with the intermediate gear 26. Rack 1 42 and rack 28 are respectively installed on both sides of shaft 1 17 or shaft 2 15. The motor 24 drives the drive gear 25 to rotate, which in turn drives the intermediate gear 26 to rotate, which in turn drives shaft 1 17 to rotate, which in turn drives shaft 2 15 to rotate, which in turn drives gear 1 22 and gear 2 29 to rotate, which in turn drives the corresponding front locking pin 4 and rear locking pin 11 to slide up and down. Since rack 1 42 and rack 2 28 are respectively installed on both sides of shaft 1 17 or shaft 2 15, when the front locking pin 4 slides up, the rear locking pin 11 slides down, and vice versa.
[0052] The support mechanism consists of several roller mechanisms 3 located on the lower sides of both sides of the rectangular frame 18. Each roller mechanism 3 includes a lower side plate, which is mounted on the upper side of the rectangular frame 18. Rollers are mounted on the lower side of the lower side plate, and the lower side plate is a retractable plate.
[0053] Working principle: During construction, the equipment is placed in the buried channel. The distance between the partition plate 14 and the bottom of the buried channel is adjusted according to the required thickness of the fine sand layer. If the support mechanism is the track 1, it can be achieved by adjusting the installation height of the track 1. If the support mechanism is the roller mechanism 3, the roller mechanism 3 can be set in the telescopic structure for easy adjustment of the distance. In the initial state, a layer of fine sand meeting the required thickness is laid at the starting end of the burial channel. Then, the main body 2 is moved to the point where the laid fine sand layer is lifted, and the separating mechanism is slid to the outermost side away from the rectangular frame 18, so that the separating mechanism is positioned on the upper surface of the laid fine sand layer. Next, sand baffle plate 19 and sand baffle plate 16 are inserted into the front slide groove 33 and rear slide groove 34 respectively. At this time, sand baffle plate 19 inserted into the front slide groove 33 is positioned between the two sides of the U-shaped slider 36, and sand baffle plate 16 in the rear slide groove 34 is close to the end face of the pre-laid fine sand layer. Additionally, the front locking pin 4 is inserted into the bottom surface of the burial channel. The rectangular frame 18 is locked. Then, fine sand is filled between the sand baffle 19 and sand baffle 2 16 inside the rectangular frame 18 until the fine sand exceeds the sand leakage hole 40. In addition, the gap between the end face of the pre-laid fine sand layer and the sand baffle 2 16 needs to be filled with fine sand through the sand leakage hole 40 until the fine sand is flush with the lower side of the sand leakage hole 40. Then, the electric telescopic rod 10 and the electric telescopic rod 28 are activated to pull out the sand baffle 2 16 on the rear side and insert it forward into the front slide groove 33. At this time, the U-shaped slider 36 is completely squeezed into the U-shaped groove 37, releasing the lock on the sand baffle 19. At the same time, the top block 30 is pressed against the side of the sand baffle 2 16. Then, the electric telescopic rod 28 retracts. Since the free end of the electric telescopic rod 28 is fixed to the sand baffle 216 through the cooperation of the electromagnet 7 and the metal block, and the sand baffle 216 is limited by the rectangular frame 18, when the electric telescopic rod 28 retracts, it will drive the partition plate 14 to slide forward, and the excess fine sand will be separated on the partition plate 14. Then, through the interlocking mechanism, the front locking pin 4 moves upward to release the lock on the rectangular frame 18, and then the locking pin 11 moves downward to insert into the bottom surface of the buried channel to lock the partition mechanism. Then, the electric telescopic rod 28 extends. At this time, the electric telescopic rod 28 will push the rectangular frame 18 forward. After the movement begins, since the sand baffle 19 is released from the lock between it and the rectangular frame 18, the sand baffle 19 remains in its original position and slides along the slide groove 6 as the rectangular frame 18 moves. (Because the fine sand cross-section after laying has a certain adhesion to the sand baffle plate 19, it can remain unmoved when the rectangular frame 18 moves, and can only slide along the slide groove 6. As an example, the sand baffle plate 19 can be kept in its original position by applying external force to it.) The excess fine sand on the partition plate 14 is pushed to the unlaid area in the front rectangular frame 18 by the pushing of the sand scraper 45. The fine sand layer under the partition plate 14 is the fine sand layer of the required thickness. When the sand baffle plate 19 reaches the position of the rear slide groove 34, the electric telescopic rod 28 is stopped and the electric telescopic rod 28 is disengaged from the sand baffle plate 26 and retracted. Then the rectangular frame 18 is locked by the interlocking mechanism, and then the next section of fine sand layer laying operation is carried out until the entire buried channel is laid.
