Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a horizontal pipe opening and closing device. Background Technology
[0002] In the field of water conservancy engineering, horizontal pipes, as a common water conveyance or control structure, are widely used in facilities such as reservoirs and canals. They regulate water levels and control water flow by installing gates at different heights. Horizontal pipes are usually arranged at an angle, and gates are spaced along the length of the pipe. The opening and closing of the gates directly affects the operational efficiency and safety of the water conservancy facilities.
[0003] In existing technologies, the opening and closing of horizontal pipe gates mostly rely on manual operation or simple mechanical devices. Manual operation requires operators to move along the horizontal pipe and operate each gate individually, which is not only labor-intensive and inefficient but also poses a high safety risk due to the need to work in water-adjacent areas. Existing mechanical opening and closing devices employ the following structure: a track is set on the horizontal pipe body, and a reciprocating trolley is mounted on the track. The trolley has a swingable steel hook, the end of which engages with the gate handle. A winch pulls a steel wire rope to move the trolley along the track, thereby opening the gate. Simultaneously, an additional independent steel wire rope is required to connect the steel hook; pulling this steel wire rope controls the swing of the hook, causing it to engage with the gate handle for locking.
[0004] However, controlling the steel hook with a wire rope has the following drawbacks: Firstly, the flexibility of the wire rope makes it difficult to precisely control the swing amplitude of the steel hook; secondly, the inherent swing inertia of the steel hook further increases the difficulty of control. This means that each time the gate is opened, a considerable amount of time is required to adjust and engage the steel hook on the gate handle, and in more severe cases, manual assistance is necessary. This not only prolongs the opening and closing operation time but also increases labor costs, making the overall operation time-consuming and labor-intensive, and seriously affecting the gate's opening efficiency.
[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content
[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a horizontal pipe opening and closing device, which aims to solve the technical problems of low alignment accuracy between the steel hook and the gate handle and low gate opening efficiency in the prior art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A horizontal tube opening and closing device, comprising:
[0009] The track is installed on the horizontal tube and extends along the inclined direction of the horizontal tube;
[0010] The trolley is slidably connected to the track, and the trolley is equipped with a first support and a second support.
[0011] A winch, installed at the upper end of a horizontal tube, is used to drive a trolley to move along a track.
[0012] A steel hook is rotatably connected to the first support. One end of the steel hook is provided with a hook part that extends to the front of the trolley. The hook part acts on the gate handle. The other end of the steel hook is provided with a first counterweight.
[0013] The lever is rotatably connected to the second support. One end of the lever is provided with a lifting end that extends to the outside of the trolley, and the other end is provided with a mounting seat. A second counterweight is provided on the lever between the lifting end and the second support.
[0014] The locking assembly is rotatably connected to the mounting base, and the output end of the locking assembly is provided with a locking block with an inverted T-shaped structure.
[0015] A locking seat, located inside the trolley and below the locking assembly, has an inverted T-shaped positioning groove on its top; and
[0016] The lifting mechanism is installed on the horizontal tube. The output end of the lifting mechanism is equipped with a lifting rod that slides vertically up and down along the track. The lifting rod is used to lift the lifting end of the lever upward so that the lever swings and presses down the steel hook. The mounting base moves down with the lever swinging, and whenever the locking block contacts the positioning groove, the locking block rotates 90° to lock in the positioning groove or disengage from the positioning groove.
[0017] Furthermore, the locking assembly includes a core column, a guide sleeve, and an outer sleeve arranged sequentially from the inside out. The outer sleeve is rotatably connected to the mounting base, and the rotation center line of the outer sleeve and the mounting base, as well as the rotation center line of the second support, are parallel to the lever. The guide sleeve has a guide groove on its peripheral wall, which includes four sequentially spliced inverted V-shaped grooves. The core column has several first short columns that slide along the guide grooves on its peripheral wall. A locking block is located at the bottom of the core column. When the core column and the outer sleeve move relative to each other, the first short columns slide along one of the inverted V-shaped grooves, and the locking block rotates 90° with the core column.
[0018] Furthermore, the guide sleeve includes an upper limit sleeve and a lower limit sleeve, and the guide groove is formed by a first gap between the upper limit sleeve and the lower limit sleeve; the outer sleeve locks the positions of the upper limit sleeve and the lower limit sleeve respectively by a number of locking screws.
[0019] Furthermore, the inverted V-shaped groove includes a sliding section, a buffer section, and a sliding out section connected in sequence. The width of the sliding section gradually decreases in the upward direction, the buffer section extends in the vertical direction, and the width of the sliding out section gradually decreases in the downward direction. The upper end of the sliding section is connected to the side wall of the buffer section, and the upper end of the sliding out section is connected to the lower end of the buffer section.
[0020] Furthermore, the outer casing has two symmetrically arranged rotating pins on its periphery; the mounting base has a rectangular frame structure, the locking assembly is located inside the mounting base, and the two rotating pins are rotatably connected to the corresponding sides of the mounting base.
[0021] Furthermore, the locking seat includes a base disposed inside the trolley, two symmetrically disposed legs on the base, and a locking block rotatably connected to the two legs. A positioning groove is formed on the locking block, and the rotation center line of the locking block and the legs and the locking assembly are parallel to the rotation center line of the mounting seat.
[0022] Furthermore, the top of the support leg is provided with a limiting part extending above the locking block, and there is a second gap between the limiting part and the locking block.
[0023] Furthermore, the lifting mechanism also includes:
[0024] A fixed frame is installed on the horizontal tube and extends along the inclined direction of the horizontal tube; the fixed frame is slidably connected to a transmission rod;
[0025] A drive translation assembly, installed at the upper end of the horizontal tube, is connected to a transmission rod and is used to drive the transmission rod to reciprocate and translate; and
[0026] Several lifting plates are spaced apart on the transmission rod, and each lifting plate has an inclined groove.
[0027] The lifting rod includes several vertical sections that slide vertically up and down along the track and a horizontal section fixed at the top of all the vertical sections. Each vertical section is provided with a second short column that slides along the inclined groove. The horizontal section is used to push the lifting end of the lever upward.
[0028] Furthermore, the front side of the trolley is provided with several push blocks, each push block is provided with an inclined surface, the inclined surface is used to act on the gate handle.
[0029] Furthermore, the track is configured as two tracks, and the front side of the trolley is provided with two shovel blocks, one of which contacts the surface of one track.
[0030] Beneficial effects:
[0031] This utility model provides a horizontal pipe opening and closing device. By using the lifting rod of the lifting mechanism to push the lifting end of the lever, the locking component and the locking seat can be flexibly controlled for locking and unlocking. On the one hand, the lever presses down on the steel hook to precisely control its swing amplitude, ensuring that the hook is reliably engaged with the gate. On the other hand, the lever can automatically release the position lock of the steel hook, so that the steel hook swings synchronously with the gate opening, ensuring a smooth gate opening process. The entire operation does not require manual adjustment, which greatly shortens the gate opening and closing operation time. Moreover, the lifting rod extends along the length of the horizontal pipe and can act on the lever on the trolley at any position on the horizontal pipe, improving its applicability.

[0046] Please see Figures 1 to 11As shown, this utility model provides a horizontal pipe opening and closing device, including: a track 1, a trolley 2, a winch, a steel hook 3, a lever 4, a locking assembly 5, a locking seat 6, and a lifting mechanism 7; the track 1 is installed on the horizontal pipe and extends along the inclined direction of the horizontal pipe; the trolley 2 is slidably connected to the track 1, and the trolley 2 is provided with a first support 21 and a second support 22; specifically, a roller 23 is rotatably connected to the trolley 2, and the roller 23 is slidably connected to the upper surface of the track 1 to realize the reciprocating translation of the trolley 2 along the track 1; the winch is installed at the upper end of the horizontal pipe to drive the trolley 2 to move along the track 1; the steel hook 3 is rotatably connected to the first support 21, one end of the steel hook 3 is provided with a hook part 31 extending in front of the trolley 2, the hook part 31 acts on the gate handle, and the other end of the steel hook 3 is provided with a first counterweight 32; the lever 4 is rotatably connected to the second support 22, one end of the lever 4 is provided with an extension The lifting end 41 extends to the outside of the trolley 2, and its other end is provided with a mounting seat 42. The lever 4 is provided with a second counterweight 43 located between the lifting end 41 and the second support 22. The locking assembly 5 is rotatably connected to the mounting seat 42. The output end of the locking assembly 5 is provided with a locking block 51 with an inverted T-shaped structure. The locking seat 6 is located inside the trolley 2 and below the locking assembly 5. The top of the locking seat 6 is provided with a positioning groove 61 with an inverted T-shaped structure. The lifting mechanism 7 is installed on the horizontal tube. The output end of the lifting mechanism 7 is provided with a lifting rod 71 that slides vertically up and down with the track 1. The lifting rod 71 is used to lift the lifting end 41 of the lever 4 upward so that the lever 4 swings and presses down the steel hook 3. The mounting seat 42 moves the locking assembly 5 downward as the lever 4 swings. Whenever the locking block 51 contacts the positioning groove 61, the locking block 51 rotates 90° to lock in the positioning groove 61 or disengage from the positioning groove 61.
[0047] The winch described above is existing technology and is not shown in the accompanying drawings. Its specific structure and working principle will not be described in detail. The winch is connected to the rear of the trolley 2 via a wire rope 10. When the winch winds up the wire rope 10, the trolley 2 slides upward along the track 1 due to the traction force of the wire rope 10; when the winch unwinds the wire rope 10, the trolley 2 slides downward along the track 1 due to its own weight.
[0048] During operation, the winch unwinds the wire rope 10, causing the trolley 2 to move downwards along the track 1. When the trolley 2 reaches the target gate, the winch stops operating. At this time, the steel hook 3 remains balanced under the action of the first counterweight 32, and its front hook 31 is in an upward position relative to the gate handle. The locking block 51 of the locking assembly 5 is parallel to the positioning groove 61 of the locking seat 6.
[0049] Subsequently, the lifting mechanism 7 is activated, and its output lifting rod 71 slides upward perpendicularly to the track 1, lifting the lifting end 41 of the lever 4, causing the lever 4 to rotate clockwise around the second support 22; during the rotation of the lever 4, the mounting base 42 drives the locking assembly 5 to move downward synchronously, and at the same time, the lever 4 applies downward pressure to the steel hook 3, causing the steel hook 3 to rotate around the first support 21, and the hook part 31 at the front end of the steel hook 3 swings downward accordingly. Figure 6 , 7 As shown, as the locking assembly 5 continues to move downward, the inverted T-shaped block 51 gradually approaches the inverted T-shaped positioning groove 61 at the top of the locking seat 6. After contacting the positioning groove 61, the block 51 automatically rotates 90° to form a perpendicular position with the positioning groove 61, thus achieving stable locking. At this time, the positions of the lever 4 and the steel hook 3 are fixed, and the hook 31 is precisely pressed down to the gate handle.
[0050] Next, as Figure 1 , 2 The winch starts winding up the wire rope 10, pulling the trolley 2 upward along the track 1. During the movement, the hook 31 engages with the gate handle. At this time, the lifting mechanism 7 starts again, and the lifting rod 71 lifts the lifting end 41 of the lever 4 again. The mounting base 42 drives the locking assembly 5 to move downward a certain distance, such as... Figure 8 , 9 As shown, the locking block 51 contacts the positioning groove 61 and automatically rotates 90°, restoring its parallel position to the positioning groove 61 to disengage from the lock. Under the action of the second counterweight 43, the lever 4 rotates counterclockwise around the second support 22, releasing the position lock on the steel hook 3. The steel hook 3 then tends to rise upwards under the action of the first counterweight 32, ensuring that the hook 31 is stably engaged with the gate handle. As the trolley 2 continues to move upwards, the hook 31 drives the gate to swing upwards, completing the gate opening action.
[0051] After the gate is fully opened, the hook 31 is in a downward state due to the weight of the gate. When it is necessary to release the hook 31 from the handle, the winch unwinds the wire rope 10, causing the trolley 2 to move down a certain distance. The hook 31 moves forward with the trolley 2 and automatically disengages from the gate handle. At the same time, the steel hook 3 returns to balance under the weight of the first counterweight 32, and the hook 31 returns to an upward state relative to the gate handle, thus achieving disengagement. If the hook 31 cannot disengage automatically during the disengagement process, the lifting mechanism 7 can be operated again to lock the locking block 51 of the locking assembly 5 into the positioning groove 61 of the locking seat 6. At this time, the lever 4 locks the steel hook 3 in a downward swing state, and then drives the trolley 2 to move forward. After the hook 31 is disengaged, the lifting mechanism 7 can be operated again to disengage the locking block 51 from the positioning groove 61. The lever 4 releases the position lock of the steel hook 3, and the steel hook 3 automatically returns to balance under the action of the first counterweight 32. The hook 31 returns to the upward state, completing the disengagement.
[0052] By pushing the lifting rod 71 of the lifting mechanism 7 upwards to lift the lifting end 41 of the lever 4, the locking component 5 and the locking seat 6 can be freely switched between locked and unlocked states. This allows for precise control of the swing amplitude of the steel hook 3 by pressing down on the lever 4, ensuring reliable engagement between the hook 31 and the gate. Simultaneously, the lever 4 automatically releases the position lock on the steel hook 3, allowing it to swing synchronously with the gate opening, ensuring a smooth opening process. The entire operation requires no manual adjustment, significantly shortening the opening and closing time. Furthermore, the lifting rod 71 extends along the length of the horizontal pipe, allowing it to act on the lever 4 at any position on the trolley 2 of the horizontal pipe, thus enhancing its applicability.
[0053] It should be noted that the opening width of the positioning groove 61 is greater than the width of the locking block 51 and less than the length of the locking block 51. The width of its inner cavity is greater than the length of the locking block 51, so that when the locking block 51 is parallel to the positioning groove 61, the locking block 51 can smoothly enter the positioning groove 61. When the locking block 51 is rotated 90° and is perpendicular to the positioning groove 61, the locking block 51 is locked in the positioning groove 61.
[0054] In a preferred embodiment, see [reference] Figure 6-8 The locking assembly 5 includes a core post 52, a guide sleeve 53, and an outer sleeve 54, which are sequentially arranged from the inside out. The outer sleeve 54 is rotatably connected to the mounting base 42, and the rotation center line of the outer sleeve 54 and the mounting base 42 and the rotation center line of the second support 22 are parallel to the lever 4. The peripheral wall of the guide sleeve 53 is provided with a guide groove 55, which includes four inverted V-shaped grooves 551 that are sequentially spliced together. The peripheral wall of the core post 52 is provided with a plurality of first short posts 521 that slide along the guide grooves 55. The locking block 51 is located at the bottom of the core post 52. When the core post 52 and the outer sleeve 54 move relative to each other, the first short posts 521 slide along one of the inverted V-shaped grooves 551, and the locking block 51 rotates 90° with the core post 52.
[0055] In the initial state, lever 4 is in an unbalanced state due to the action of the second counterweight 43. At this time, locking assembly 5 is lifted, and the locking block 51 with an inverted T-shaped structure at the bottom of core column 52 is parallel to the inverted T-shaped positioning groove 61 at the top of locking seat 6.
[0056] When the lifting rod 71 lifts the lifting end 41 of the lever 4 upwards, the lever 4 rotates clockwise around the second support 22, and the mounting seat 42 drives the locking assembly 5 to move downwards as a whole. At this time, the lever 4 simultaneously presses down the steel hook 3 to make it swing downwards; the locking block 51 at the bottom of the core column 52 first abuts against the positioning groove 61 of the locking seat 6. As the lever 4 continues to rotate, the outer sleeve 54 and the core column 52 move relative to each other. The first short column 521 on the core column 52 slides along the path of the inverted V-shaped groove 551 corresponding to the guide groove 55. Combined with the tendency of the lever 4 to rotate counterclockwise around the second support 22 under the gravity of the second counterweight 43 after it is lifted, with the guide groove 55 as a reference, it is ensured that the first short column 521 of the core column 52 slides upwards first and then downwards, completing the movement path of one inverted V-shaped groove 551, causing the core column 52 to complete the lifting and lowering movement relative to the outer sleeve 54 and rotate 90° around its own axis. Figure 6 As shown, at this time, the locking block 51 rotates 90° with the core column 52 and is perpendicular to the positioning groove 61. It is locked into the positioning groove 61 to complete the locking action of the locking component 5 and the locking seat 6, thereby locking the state of the lever 4 pressing down the steel hook 3, ensuring that the steel hook 3 is in the swing position, and ensuring that when it moves forward with the trolley 2, the hook 31 can be smoothly locked on the gate handle.
[0057] When it is necessary to cancel the locking of position 3 of the steel hook, such as Figure 8 As shown, the lifting rod 71 lifts the lifting end 41 of the lever 4 upwards again, and the lever 4 rotates clockwise around the second support 22. The mounting base 42 then moves the locking assembly 5 downwards by a distance (this distance is the height of the inverted V-shaped groove 551 in the vertical direction). The outer sleeve 54 and the core column 52 move relative to each other again. With the guide groove 55 as a reference, the first short column 521 on the core column 52 repeats the process of sliding upwards and then downwards, completing the movement path of one inverted V-shaped groove and causing the core column 52 to rotate 90° around its own axis. This causes the locking block 51 to rotate with the core column 52 and become parallel to the positioning groove 61, thus disengaging from the positioning groove 61 and completing the unlocking action. At the same time, the lever 4 rotates counterclockwise around the second support 22 under the gravity of the second counterweight 43. The mounting base 42 then moves the locking assembly 5 upwards away from the locking seat 6, releasing the position lock on the steel hook 3. Four sequentially connected inverted V-shaped grooves 551 form a continuous guide path. Whenever the core post 52 slides up and down relative to the outer sleeve 54, it can force the core post 52 to rotate 90° to meet the needs of locking and unlocking the locking assembly 5 for multiple cycles, and achieve precise locking of the swing position of the steel hook 3.
[0058] Preferably, there are two first short columns 521, which are symmetrically arranged on the peripheral wall of the core column 52. The two first short columns 521 are correspondingly arranged in two inverted V-shaped grooves 551 with opposite positions, so that the core column 52 is subjected to balanced force during movement.
[0059] Further, see Figure 10 The guide sleeve 53 includes an upper limit sleeve 531 and a lower limit sleeve 532. The guide groove 55 is formed by a first gap between the upper limit sleeve 531 and the lower limit sleeve 532. The outer sleeve 54 locks the positions of the upper limit sleeve 531 and the lower limit sleeve 532 respectively by a number of locking screws 541. The guide sleeve 53 is composed of a split upper limit sleeve 531 and a lower limit sleeve 532, so that the complex guide groove 55 structure is transformed into the end face processing of two split parts. By controlling the end face mating of the upper limit sleeve 531 and the lower limit sleeve 532, the required guide groove 55 can be formed, which greatly reduces the processing difficulty of the guide groove 55 and the assembly difficulty of the guide sleeve 53 with the core column 52 and the outer sleeve 54. During assembly, the upper limit sleeve 531 can be first placed on the core post 52 and then assembled into the outer sleeve 54. Subsequently, the lower limit sleeve 532 is placed between the core post 52 and the outer sleeve 54. Finally, multiple locking screws 541 are used to tighten the upper limit sleeve 531 and the lower limit sleeve 532 from the circumferential direction to achieve a stable positioning of the guide sleeve 53 in the outer sleeve 54.
[0060] Preferably, both the upper limit sleeve 531 and the lower limit sleeve 532 have shoulders 533 at their ends furthest from the guide groove 55, which abut against the end face of the outer sleeve 54. By providing the shoulders 533, the guide sleeve 53 can be limited in the axial direction. When the upper limit sleeve 531 and the lower limit sleeve 532 are assembled into the outer sleeve 54, the shoulders 533 abut tightly against the end face of the outer sleeve 54, thereby limiting the upper limit sleeve 531 from moving upward or the lower limit sleeve 532 from moving downward, and preventing the guide groove 55 from shifting due to the axial movement of the guide sleeve 53. At the same time, the cooperation between the shoulders 533 and the end face of the outer sleeve 54 can help position the assembly position of the upper limit sleeve 531 and the lower limit sleeve 532, ensuring that the first gap formed between them (i.e., the guide groove 55 is accurately sized) maintains a stable fit with the first short post 521 of the core post 52, providing a reliable guiding reference for the subsequent sliding and rotation of the core post 52.
[0061] Furthermore, see Figure 10The inverted V-shaped groove 551 includes a sliding section 5511, a buffer section 5512, and a sliding section 5513 connected in sequence. The width of the sliding section 5511 gradually decreases in the upward direction, providing a progressive guide for the first short column 521 of the core column 52, allowing the first short column 521 to slide smoothly into the buffer section 5512. The buffer section 5512 extends vertically, providing a brief vertical movement space for the first short column 521, achieving a smooth transition of the sliding path. The width of the sliding section 5513 gradually decreases in the downward direction. The upper end of the sliding section 5511 is connected to the side wall of the buffer section 5512, and the upper end of the sliding section 5513 is connected to the lower end of the buffer section 5512, allowing the first short column 521 to naturally transition from the buffer section 5512 to the sliding section 5513 during downward sliding. In addition, the lower end of the sliding section 5513 of the first inverted V-groove 551 is joined with the lower end of the sliding section 5511 of the second inverted V-groove 551 to form a continuous closed guide path, ensuring that the first short column 521 can slide smoothly along the guide groove 55 in multiple locking-unlocking cycles, avoiding jamming or path interruption.
[0062] In the above embodiments, see Figure 8 The outer casing 54 has two symmetrically arranged rotating pins 542 on its peripheral wall; the mounting base 42 is a rectangular frame structure, and the locking assembly 5 is located inside the mounting base 42. The two rotating pins 542 are rotatably connected to the corresponding sides of the mounting base 42. The locking assembly 5 can swing freely around the axis of the rotating pins 542. When the lever 4 rotates around the second support 22, the mounting base 42 swings synchronously with the lever 4. Under its own gravity, the locking assembly 5 can always maintain an approximately vertical state, unaffected by the angular deviation caused by the swing of the lever 4. This ensures that the locking block 51 at the bottom of the core 52 and the positioning groove 61 of the locking seat 6 are always in the same vertical direction, providing a stable spatial posture guarantee for the precise insertion or disengagement of the locking block 51 during locking and unlocking.
[0063] In the above embodiments, see Figure 7 The locking seat 6 includes a base 62 disposed within the trolley 2, two symmetrically arranged legs 63 on the base 62, and a locking block 64 rotatably connected to the two legs 63. A positioning groove 61 is formed on the locking block 64, and the rotation center line of the locking block 64 and the legs 63, as well as the rotation center line of the locking assembly 5, are parallel to the mounting base 42. During actual movement, when the locking assembly 5 experiences angular sway due to motion inertia, the locking block 64 can adaptively rotate slightly according to the contact pressure of the locking block 51, thereby adjusting the angle and posture of the positioning groove 61 in real time to compensate for the alignment deviation between the locking block 51 and the positioning groove 61, ensuring that the contact surface between the bottom of the locking block 51 and the positioning groove 61 always remains stably fitted, further improving the smoothness and reliability of the locking action.
[0064] Further, see Figure 7The top of the support leg 63 is provided with a limiting part 631 extending above the locking block 64, and a second gap 632 is provided between the limiting part 631 and the locking block 64. The second gap 632 is set to the maximum range within which the locking block 64 can achieve adaptive angle adjustment. When the locking block 64 rotates due to the contact pressure of the locking block 51, the limiting part 631 can form a rigid block when it swings to a preset angle, preventing the locking block 64 from excessively swaying due to inertia or excessive external force, and ensuring that its angle adjustment is always within a reasonable range. At the same time, since the locking assembly 5 is located in the mounting base 42 of the rectangular frame structure, a third gap is left between the peripheral wall of the locking assembly 5 and the inner side wall of the mounting base 42 on the swinging vertical plane. This third gap is used to limit the swing amplitude of the locking assembly 5. The coordinated constraint of the second gap 632 and the third gap ensures both the adaptive adjustment space of the locking block 64 and the locking component 5 and prevents them from deviating from the preset mating trajectory due to excessive swaying. This ensures that the locking block 51 is always aligned with the positioning groove 61 during the movement and successfully completes the embedding action.
[0065] In a preferred embodiment, see [reference] Figure 11 The lifting mechanism 7 further includes: a fixed frame 72, a drive translation component 74, and several lifting plates 75. The fixed frame 72 is installed on the horizontal tube and extends along the inclined direction of the horizontal tube. The fixed frame 72 is slidably connected to a transmission rod 73. Specifically, multiple fixed frames 72 are provided, and the multiple fixed frames 72 are arranged at intervals along the inclined direction of the horizontal tube. The transmission rod 73 is slidably connected to the multiple fixed frames 72. The drive translation component 74 is installed at the upper end of the horizontal tube and is connected to the transmission rod 73 for driving the transmission rod 73 to reciprocate. Several lifting plates 75 are spaced apart on the transmission rod 73, and each lifting plate 75 has an inclined groove 751. The lifting rod 71 includes several vertical sections 711 that slide vertically up and down perpendicular to the track 1 and horizontal sections 712 fixed at the top of all vertical sections 711. Each vertical section 711 has a second short column 713 that slides along the inclined groove 751. The horizontal section 712 is used to push the lifting end 41 of the lever 4 upward. Specifically, the track 1 has multiple spaced fixed seats 11 on the side near the transmission rod 73, and a vertical section 711 is slidably connected to the fixed seat 11.
[0066] When the drive translation component 74 drives the transmission rod 73 to translate along the extension direction of the track 1, the lifting plate 75 moves synchronously with the transmission rod 73. The inclined groove 751, through its sliding engagement with the second short column 713, converts the horizontal displacement of the transmission rod 73 into the vertical lifting motion of the lifting rod 71—that is, the inclined surface 81 of the inclined groove 751 forces the second short column 713 to drive the vertical section 711 to slide upward, so that the horizontal section 712 acts on the lifting end 41 of the lever 4. By setting multiple lifting plates 75 and multiple vertical sections 711 with corresponding sliding engagements of the second short column 713, the horizontal section 712 of the lifting rod 71 can perform a smooth lifting motion. At this time, no matter where the trolley 2 is on the track 1, the horizontal section 712 can push the lifting end 41 of the lever 4 upward through the above transmission logic, ensuring that the lifting operation of the lever 4 can be stably completed throughout the entire operating range, thereby improving the adaptability and automation level.
[0067] The aforementioned driving translation component 74 is implemented using existing technology, and its specific structure and working principle will not be elaborated further. Specifically, various mature transmission forms can be selected: one is an electric push rod, whose extended end is connected to the end of the transmission rod 73, and the transmission rod 73 is directly driven to reciprocate and translate through the extension and retraction of the electric push rod; the other is a combination structure of a rotary motor and a gear and rack transmission mechanism, in which the output shaft of the rotary motor is connected to the input end of the gear and rack transmission mechanism, and the output end of the gear and rack transmission mechanism is connected to the transmission rod 73. The rotary motor drives the gear to rotate, and the gear meshes with the rack to drive the rack to perform linear motion, thereby driving the transmission rod 73 to reciprocate and translate. Thirdly, a combination structure of a rotary motor, gear transmission assembly, and ball screw transmission mechanism can be adopted. The output shaft of the rotary motor, the gear transmission assembly, and the input end of the ball screw transmission mechanism are connected in sequence. The output end of the ball screw transmission mechanism is connected to the transmission rod 73. The rotary motor drives the ball screw nut to rotate through the gear transmission assembly. The meshing transmission between the ball screw nut and the ball screw is converted into the linear motion of the ball screw, thereby driving the transmission rod 73 to reciprocate. The above-mentioned existing technical solutions can all meet the smooth driving requirements of the transmission rod 73, and the appropriate model can be selected according to the load size, speed requirements, and installation space in the actual working conditions.
[0068] In a preferred embodiment, see [reference] Figure 5The trolley 2 has several push blocks 8 on its front side, each push block 8 having an inclined surface 81 that acts on the gate handle. When the gate needs to be closed, the winch unwinds the wire rope 10, driving the trolley 2 to move downwards along the track 1, gradually bringing the trolley 2 closer to the opened gate. As the trolley 2 continues to move downwards, the inclined surface 81 on the push block 8 first contacts the gate handle. Due to the inclined guiding effect of the inclined surface 81, the thrust generated by the downward movement of the trolley 2 is converted into an upward thrust on the gate handle through the inclined surface 81, causing the gate to slowly rotate around its own axis. During this process, the steel hook 3 keeps the hook part 31 in an upward state under the gravity of the first counterweight 32, avoiding interference with the gate handle. At this time, the gate continues to rotate under its own gravity, eventually fitting tightly with the hole in the horizontal pipe, completing the gate closure. The entire process can complete the automatic closure of the gate without manual assistance, and in conjunction with the automated operation of the device to open the gate, it realizes the automatic opening and closing of the gate.
[0069] In a preferred embodiment, see [reference] Figure 5 The device comprises two tracks 1, and two shovel blocks 9 are provided on the front side of the trolley 2, with one shovel block 9 corresponding to one track 1 surface. Preferably, the front end of the shovel block 9 is designed to be inclined. When the trolley 2 moves downward along the track 1, the two shovel blocks 9 move downward simultaneously, shoveling and pushing the sand, gravel, silt and other debris accumulated on the track 1 forward, so that the debris is removed from the surface of the track 1, avoiding the debris from remaining in the contact area between the track 1 and the roller 23 of the trolley 2. This eliminates the obstruction of the trolley 2's movement by the debris on the track 1, ensuring that the trolley 2 moves smoothly along the two tracks 1 without any jamming, thus improving the stability and reliability of the device operation.
