Description

Technical Field

[0001] The present invention relates to the technical field of construction elevators, and in particular to a semi-automatic construction elevator door. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the continuous advancement of construction technology, super-high-rise buildings are becoming increasingly common. During the construction of such buildings, the vertical transportation of materials and personnel is a key factor influencing the progress of the project. As one of the main means of vertical transportation, the efficiency of construction elevators directly affects the construction speed, especially during the decoration and renovation stage.

[0004] To ensure the safety of personnel on each floor and in the construction elevator, construction elevators are equipped with independent floor doors and elevator car doors at each floor stop and in the elevator car, and they open and close independently. This results in a cumbersome door opening and closing process when the construction elevator stops at the construction floor (open elevator car door → lower safety partition → open floor door → load and unload materials or personnel → close floor door → latch and lock floor door → retract safety partition → close elevator car door). This cumbersome procedure results in long stop times for each construction unit on a single floor, directly affecting elevator transportation efficiency.

[0005] To this end, the present invention provides a semi-automatic construction elevator door to solve the above problems. Summary of the Invention

[0022] When the second transmission block does not press the corresponding first transmission block, the second transmission block cross-engages with the through-groove of the first transmission block through the first groove;

[0023] When the second transmission block squeezes the corresponding first transmission block, the second transmission block contacts the first pressure-bearing slope through the pressure slope, forcing the first transmission block to drive the clamping block out of the clamping slot. At this time, the first groove is misaligned with the through groove.

[0024] Furthermore, a first spring is sleeved on the outer side of the pressure rod, and the two ends of the first spring are respectively connected to the side wall of the second transmission block and the corresponding inner wall of the door seat. When the second transmission block squeezes the corresponding first transmission block, the first spring stretches and deforms;

[0025] A second spring is provided between the first transmission block, which is close to one end of the car, and the inner wall of the door seat. When the first transmission block drives the clamping block to disengage from the clamping slot, the second spring is compressed and deformed.

Under the limiting action of the limiting block and the limiting slot, the second transmission gear can move from one end of the limiting slot close to the car to the other end thereof to engage with the third transmission gear. The bevel gear drive cylinder cooperates with the screw to make the push plate push the moving block to move toward the direction close to the car, so that the pressure block disengages from the second slot and returns to the first slot;

[0034] When the landing door is deflected and parallel to the elevator door, the clamping slot rotates synchronously with the disc body to a position where the clamping block can engage.

[0035] Furthermore, a fourth spring is provided in the limiting groove, and two ends of the fourth spring are respectively connected to the outer wall of the limiting block and the corresponding groove wall of the limiting groove. When the limiting block moves in the limiting groove in a direction close to the third transmission gear, the fourth spring is compressed and deformed;

When construction personnel or materials need to enter the corresponding floor from the car, the safety partition is automatically deflected and placed in the stairwell of the corresponding floor and the corresponding floor door is automatically opened by relying solely on the translation effect of the elevator door when it is opened. After the construction personnel or materials enter the corresponding floor, the position between the floor doors after closing can be automatically locked by relying solely on the deflection action of the floor door when it is closed.

[0058] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the embodiments described are only some embodiments of the invention, not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the invention.

[0059] Please combine Figures 1 to 11 .

[0060] A semi-automatic construction elevator door comprises two elevator doors 3 which are installed on a car 1 so as to be slidable and open to each other. Safety partitions 4 which are perpendicular to the slidable direction of the elevator doors 3 are rotatably provided on both sides of the car 1.

[0061] Two normally closed landing doors 5 parallel to the elevator door 3 are provided at the stairwell 2 on each floor so as to be deflectable and openable.

[0062] There are also action devices at the two stairwells on each floor.

[0063] The action device includes two pressure rods 15 and an unlocking mechanism. The two pressure rods 15 are elastically inserted on both sides of the ladder entrance 2 and parallel to the translation direction of the ladder door 3. The pressure rods 15 are in contact and pressure fit with the corresponding safety partitions 4.

[0064] The actuating device further includes an unlocking mechanism and a self-locking mechanism arranged in the ladder entrance 2, and a transmission assembly is provided on the car 1.

[0065] When the elevator door 3 is driven to open, the transmission assembly can synchronously drive the two safety partitions 4 to deflect from the car 1 and extend into the elevator entrance 2 of the corresponding floor, and respectively press the corresponding pressure rods 15 to drive the unlocking mechanism to release the normally closed state between the floor doors 5, allowing the two floor doors 5 to deflect and open to the side away from the car 1.

[0066] When the landing door 5 is driven to deflect and close, the self-locking mechanism can automatically lock the relative position of the landing door 5 when closed, so that the landing door 5 returns to the normally closed state parallel to the elevator door 3.

[0067] In specific implementation, when the elevator moves to the preselected floor, when the two elevator doors 3 are controlled to move and open, the movement of the elevator doors 3 can be achieved through the transmission component, so that the two safety partitions 4 originally located parallel to the car wall on both sides of the car 1 are deflected outward respectively, extending into the stair opening 2 of the corresponding floor, and respectively touching the corresponding pressure rods 15 in the stair opening 2, so as to drive the unlocking mechanism through the pressure rods 15, release the normally closed state between the floor doors 5, and allow the two floor doors 5 to automatically deflect and open to the side away from the car 1, so that construction personnel or materials can enter the corresponding floor.

[0068] When construction workers or materials enter the corresponding floor, the two elevator doors 3 are manually driven to return to a position parallel to the elevator doors 3. At this time, the self-locking mechanism can automatically lock the relative position of the floor doors 5 when they are closed, so that the floor doors 5 are restored to a normally closed state parallel to the elevator doors 3. Then the two elevator doors 3 are controlled to move and close horizontally. The movement of the elevator doors 3 can be controlled by the transmission component to make the safety partitions 4 in the ladder entrance 2 automatically return to the positions on both sides of the car 1 for the subsequent movement and use of the construction elevator.

[0069] The advantage of this design is that when construction personnel or materials need to enter the corresponding floor from the elevator car 1, the safety partition 4 can be automatically deflected and placed in the ladder entrance 2 of the corresponding floor and the corresponding floor door 5 can be automatically opened by relying solely on the translation effect of the elevator door 3 when it is opened. After the construction personnel or materials enter the corresponding floor, the floor door 5 can be automatically locked in the closed position by relying solely on the deflection action when the floor door 5 is closed. This can greatly shorten the opening and closing time of the construction elevator door, reduce the single-trip transportation time of the elevator, increase the daily operation of the elevator, and ultimately improve the elevator transportation efficiency, which has a significant contribution to shortening the construction period and reducing construction costs.

[0070] It should be noted that the elevator door 3 of the car 1 in this application adopts an automatic opening and closing method. Its mechanism can be divided into three categories: DC voltage-regulated speed-regulated drive, AC frequency-regulated speed-regulated drive combined with synchronous toothed belt drive, and water-magnetic synchronous motor drive combined with synchronous toothed belt drive. Among them, the DC voltage-regulated speed-regulated drive and transmission mechanism is the most common. Its principle is to utilize the excellent voltage-regulated speed-regulated performance and simple commutation characteristics of the DC motor to achieve the automatic door opening and closing function through pulley deceleration and mechanism transmission.

[0071] In one embodiment, the unlocking mechanism includes two door seats 6 respectively fixed on both sides of the ladder entrance 2. An upright first rotating column 11 is elastically rotatably provided in each door seat 6, and the outer wall of the first rotating column 11 is fixedly connected to one side of the corresponding floor door 5.

[0072] A fixed plate 8 is fixed inside the door seat 6, and a first transmission block 9 perpendicular to the pressure rod 15 is slidably inserted on the fixed plate 8. A clamping block 10 is provided at the end of the first transmission block 9 away from the car 1, and a disk body 12 is sleeved and fixed on the first rotating column 11. A clamping groove 13 that cooperates with the clamping block 10 is opened on the outer peripheral side of the disk body 12.

[0073] The two pressure rods 15 are respectively inserted into the corresponding door seats 6 . A second transmission block 14 is coaxially provided at one end of the pressure rod 15 located in the corresponding door seat 6 . The second transmission block 14 is squeezed and fitted with the corresponding first transmission block 9 .

[0074] When the safety partition 4 contacts the corresponding pressure rod 15, the second transmission block 14 is driven to squeeze the corresponding first transmission block 9, forcing the first transmission block 9 to drive the card block 10 out of the card slot 13, allowing the corresponding floor door 5 to deflect to the side away from the car 1.

[0075] In this way, when the elevator door 3 moves horizontally to open, the elevator door 3 drives the safety partition 4 to deflect to the inside of the ladder entrance 2 through the transmission assembly to press the corresponding pressure rod 15. The pressure rod 15 drives the second transmission block 14 to squeeze the corresponding first transmission block 9, forcing the first transmission block 9 to move closer to the car 1, thereby causing the blocking block 10 to disengage from the blocking slot 13, releasing the lock on the position of the disc body 12, and then the floor door 5 can be deflected to the side away from the car 1 through the first rotating column 11 to open.

[0076] It should be added that the maximum deflection angle of the floor door 5 of the present application is ninety degrees, and a door slot 7 is provided on the door seat 6 for accommodating the floor door 5 after it is opened.

[0077] In one embodiment, an insertion hole (not shown) is opened on the inner bottom wall of the door seat 6, the bottom of the first rotating column 11 is inserted into the insertion hole, and a first torsion spring (not shown) is sleeved on the outer side of the first rotating column 11, and the two ends of the first torsion spring are respectively connected to the outer wall of the first rotating column 11 and the wall of the insertion hole.

[0078] When the landing door 5 is in the normally closed state, the first torsion spring is in a compressed deformation state.

[0079] When the landing door 5 is in the open state, the first torsion spring is in a non-deformed state.

[0080] In this way, when the block 10 disengages from the slot 13 and releases the lock on the position of the disc body 12, the first rotating column 11 can automatically deflect and open to the side away from the elevator car 1 under the release of the elastic force of the first torsion spring, so as to realize the automatic opening of the floor door 5 after the elevator door 3 is opened and the safety partition 4 is deflected and extended into the ladder entrance 2.

[0081] In one embodiment, the first transmission block 9 has a through slot 18 for the second transmission block 14 to vertically pass through, and a first pressure-bearing slope 19 is provided on one side of the through slot 18. The outer side of the second transmission block 14 has a first groove 16 that can cross-engage with the through slot 18, and a notch on one side of the first groove 16 has a pressure slope 17 that slides and contacts with the first pressure-bearing slope 19.

[0082] When the second transmission block 14 is not pressed against the corresponding first transmission block 9 , the second transmission block 14 is cross-engaged with the through groove 18 of the first transmission block 9 through the first groove 16 .

[0083] When the second transmission block 14 squeezes the corresponding first transmission block 9, the second transmission block 14 contacts the first pressure-bearing slope 19 through the pressure slope 17, forcing the first transmission block 9 to drive the clamping block 10 out of the clamping slot 13. At this time, the first groove 16 and the through groove 18 are misaligned.

[0084] In this way, when the safety partition 4 has not entered the ladder opening 2 and has not pressed the pressure-bearing rod 15, the second transmission block 14 does not squeeze the corresponding first transmission block 9. The second transmission block 14 is in a cross-engaged state with the through groove 18 of the first transmission block 9 through the first groove 16. At this time, the clamping block 10 is clamped in the clamping groove 13.

[0085] When the safety partition 4 enters the stairwell 2 and contacts the pressure-bearing rod 15, the pressure-bearing rod 15 drives the second transmission block 14 to move, causing the pressure slope 17 to contact the first pressure-bearing slope 19 until the first groove 16 and the through groove 18 are misaligned with each other. This will cause the first transmission block 9 to translate toward the direction close to the car 1, so that the blocking block 10 disengages from the blocking groove 13, releasing the lock on the position of the disc 12, and then allowing the first rotating column 11 to drive the landing door 5 to open under the release of the elastic force of the first torsion spring.

[0086] In one embodiment, a first spring (not shown) is sleeved on the outside of the pressure rod 15, and the two ends of the first spring are respectively connected to the end side wall of the second transmission block 14 and the corresponding inner wall of the door seat 6. When the second transmission block 14 squeezes the corresponding first transmission block 9, the first spring is stretched and deformed.

[0087] A second spring (not shown) is provided between one end of the first transmission block 9 close to the car 1 and the inner wall of the door seat 6. When the first transmission block 9 drives the clamping block 10 to disengage from the clamping slot 13, the second spring is compressed and deformed.

[0088] In this way, the tensile deformation of the first spring can help the second transmission block 14 to move in the opposite direction and return to its cross-engaging state with the first transmission block 9 when the pressure rod 15 is not touched by the safety partition 4 and the pressure block 25 disengages from the second slot 22 and returns to the first slot 21, thereby providing avoidance space for the reverse recovery movement of the first transmission block 9.

[0089] The compression deformation of the second spring can help the first transmission block 9 to move in the opposite direction when the second transmission block 14 moves in the opposite direction and returns to the cross-engaging state with the first transmission block 9, so that the clamping block 10 can be re-engaged in the clamping groove 13, completing the locking of the position of the disk body 12, that is, realizing the position locking of the closed layer door 5.

[0090] In one embodiment, a moving block 20 capable of relative movement in the moving direction of the first transmission block 9 is elastically provided in the door seat 6, a connecting rod 24 is coaxially fixed to the end of the second transmission block 14 away from the pressure rod 15, and a pressure block 25 is provided on the side of the connecting rod 24 away from the end of the second transmission block 14. The moving block 20 has a first slot 21 for inserting the pressure block 25 on the side facing the first transmission block 9, and a second pressure slope 23 on one side of the notch of the first slot 21 is provided for sliding and extruding with the pressure block 25. A second slot 22 is provided in the moving block 20 to engage with the pressure block 25, and the second slot 22 is connected to the side of the first slot 21 close to the car 1.

[0091] In this way, when the safety partition 4 enters the ladder entrance 2 and touches the pressure-bearing rod 15, the pressure-bearing rod 15 drives the second transmission block 14 to move, which not only causes one end of the first transmission block 9 to drive the card block 10 to disengage from the card slot 13, releasing the lock on the position of the disk body 12, so that the first rotating column 11 can drive the floor door 5 to open under the release of the elastic force of the first torsion spring, but also the second transmission block 14 also drives the pressure block 25 through the connecting rod 24 to squeeze the second pressure slope 23, forcing the moving block 20 to move horizontally toward the car 1 to avoid the pressure block 25 so that the pressure block 25 can enter the first slot 21.

[0092] When the pressure block 25 is fully inserted into the first slot 21, the moving block 20 can make a reverse reset movement relative to the pressure block 25 under the action of the rebound force, so that the pressure block 25 is stuck in the second slot 22, thereby effectively maintaining the misalignment state between the second transmission block 14 and the first transmission block 9.

[0093] In one embodiment, a first telescopic rod 26 is provided between one end of the moving block 20 close to the car 1 and the inner wall of the door seat 6 , and a third spring (not shown) is sleeved on the outer side of the first telescopic rod 26 .

[0094] When the pressure block 25 presses the second pressure-bearing slope 23, the moving block 20 is forced to move closer to the car 1, and the first telescopic rod 26 and the third spring are compressed and deformed.

[0095] When the pressure block 25 is inserted into the second slot 22 , the first telescopic rod 26 and the third spring are in a non-deformed state.

[0096] In this way, the first telescopic rod 26 can be used to realize the installation and positioning of the moving block 20 in the door seat 6. At the same time, the cooperation of the first spring and the first telescopic rod 26 can realize automatic locking or automatic unlocking after the position misalignment between the second transmission block 14 and the first transmission block 9.

[0097] In one embodiment, the self-locking mechanism includes a first transmission gear 27 sleeved and fixed to the outside of the first rotating column 11. A one-eighth-circular arc-shaped limiting groove 28 is fixed in the door base 6 along the circumference of the first rotating column 11. The limiting groove 28 is located outside the first transmission gear 27 and between the first transmission block 9 and the moving block 20. The limiting groove 28 is fixed to the fixed plate 8 via a support rod.

[0098] A limit block 29 that can move relatively in its groove body is elastically provided in the limit groove 28, and a second transmission gear 30 that can move circumferentially and mesh with the first transmission gear 27 is rotatably provided on the limit block 29. A third transmission gear 31 that can mesh with the second transmission gear 30 is elastically rotatably provided in the door seat 6 located on the side of the limit groove 28 away from the first transmission gear 27, and a first bevel gear 32 is concentrically fixed on the third transmission gear 31. A cylinder 33 parallel to the first transmission block 9 is rotatably inserted on the fixed plate 8, and a second bevel gear 34 that cooperates with the first bevel gear 32 is provided at one end of the cylinder 33, and a screw 36 is threadedly inserted at the other end of the cylinder 33. A push plate 35 that can push the moving block 20 to move toward the direction close to the car 1 is fixed at one end of the screw 36, and a second telescopic rod 37 is provided between the push plate 35 and the fixed plate 8.

[0099] When the landing door 5 deflects and opens, the landing door 5 drives the first rotating column 11, the first transmission gear 27, and the second transmission gear 30 to rotate, and the second transmission gear 30 on the limit block 29 stays in the limit slot 28 near the end of the car 1.

[0100] During the deflection and closing of the driving landing door 5, the landing door 5 drives the first rotating column 11, the first transmission gear 27, and the second transmission gear 30 to rotate. Under the limiting action of the limiting block 29 and the limiting slot 28, the second transmission gear 30 can move from one end of the limiting slot 28 close to the car 1 to the other end thereof to engage with the third transmission gear 31. The bevel gear drive cylinder 33 cooperates with the screw 36 to enable the push plate 35 to push the moving block 20 toward the direction close to the car 1, so that the pressure block 25 disengages from the second slot 22 and returns to the first slot 21.

[0101] When the landing door 5 deflects and becomes parallel to the elevator door 3 , the latching slot 13 rotates synchronously with the disc 12 to a position where the latching block 10 can engage with the latching slot 13 .

[0102] In this way, when the floor door 5 is deflected and opened, the floor door 5 drives the first rotating column 11, the first transmission gear 27, and the second transmission gear 30 to rotate, and the second transmission gear 30 on the limit block 29 stays in the limit groove 28 at one end close to the car 1. At this time, the second transmission gear 30 is not in contact and meshing with the third transmission gear 31, and the push plate 35 remains stationary.

[0103] When the driving landing door 5 is deflected and closed, the landing door 5 drives the first rotating column 11, the first transmission gear 27, and the second transmission gear 30 to rotate. Under the meshing action and the limiting action of the limit block 29 and the limiting groove 28, the second transmission gear 30 moves from one end of the limiting groove 28 close to the car 1 to the other end thereof, so as to engage with the third transmission gear 31, thereby driving the third transmission gear 31 to rotate. The third transmission gear 31 drives the first bevel gear 32 and the second bevel gear 34 to drive the cylinder 33 to rotate, so that the cylinder 33 and the screw 36 interact with each other, and under the limiting action of the second telescopic rod 37, the push plate 35 moves to the movable Block 20 pushes the moving block 20 to move toward the direction of the elevator car 1, so that the second slot 22 is disengaged from the pressure block 25, and the pressure block 25 is returned to the first slot 21, releasing the engagement between the second slot 22 and the pressure block 25. In this way, when the pressure rod 15 can be reset in the reverse direction under the action of the first spring force, the second transmission block 14 and the first transmission block 9 are restored to the cross-engaged state, providing avoidance space for the reverse recovery movement of the first transmission block 9, so that the first transmission block 9 can move in the reverse direction under the action of the second spring force, so that the card block 10 is locked into the card slot 13 of the disk body 12, locking the position of the floor door 5 after closing.

[0104] In one embodiment, a fourth spring (not marked) is provided in the limiting groove 28, and the two ends of the fourth spring are respectively connected to the outer wall of the limiting block 29 and the corresponding groove wall of the limiting groove 28. When the limiting block 29 moves in the limiting groove 28 in a direction close to the third transmission gear 31, the fourth spring is compressed and deformed.

[0105] The inner bottom wall of the door seat 6 is provided with a spring hole, and the bottom of the axle of the third transmission gear 31 is inserted into the spring hole (not shown in the figure). A second torsion spring (not shown in the figure) is sleeved on the outer side of the axle of the third transmission gear 31, and the two ends of the second torsion spring are respectively connected to the outer wall of the axle of the third transmission gear 31 and the corresponding hole wall of the spring hole.

[0106] In this way, when the landing door 5 is closed, the second transmission gear 30 engages and drives the first transmission gear 27, causing the second transmission gear 30 to move through the limit block 29 toward the end of the limit slot 28 away from the car 1, thereby achieving the meshing transmission of the second transmission gear 30 to the third transmission gear 31 (this process gradually compresses the fourth spring, causing the second torsion spring to compress and deform), thereby causing the push plate 35 to push the moving block 20. Using this compressed elastic force, when the landing door 5 is driven to close, the fourth spring releases the elastic force, pushing the limit block 29 to move back to the initial position in the limit slot 28, so that the second transmission gear 30 disengages the third transmission gear 31 and follows the limit block 29 to return to the initial position. At the same time, the compressed elastic force of the second torsion spring is released, driving the cylinder 33 to rotate in the opposite direction, thereby indirectly causing the push plate 35 to move away from the moving block 20 and disengage from the moving block 20. The moving block 20 can then return to its initial position (the second pressure-bearing slope 23 is located directly below the pressure-applying block 25) under the action of the third spring.

[0107] In one embodiment, the transmission assembly includes two second rotating columns 42 uprightly arranged on both sides of the bottom of the car 1, one side of the safety partition 4 is fixed to the outer side of the corresponding second rotating column 42, and a fourth transmission gear 38 is fixed to the second rotating column 42 near the top. A rack 39 is provided on the top of the elevator door 3 away from the ladder entrance 2, which is parallel to its translation direction and cooperates with the corresponding fourth transmission gear 38.

[0108] The maximum deflection angle of the safety partition 4 is 180 degrees.

[0109] When the elevator doors 3 are closed, the safety partition 4 is located inside the car 1 and is parallel to the side wall of the car 1 .

[0110] After the ladder doors 3 are opened, the safety partition 4 is located in the corresponding ladder opening 2 and is parallel to the corresponding side wall of the ladder opening 2 .

[0111] It should be pointed out that a sliding groove (not marked) is provided on the ladder door 3 for the rack 39 to slide and engage. When the ladder door 3 is opened, the front end of the rack 39 will first contact the fourth transmission gear 38. However, at this time, under the resistance of the fourth transmission gear 38, the ladder door 3 continues to open and translate relative to the rack 39 through the sliding groove until the rack 39 is relatively displaced to a predetermined limit position in the sliding groove. At this time, the translation of the ladder door 3 as it continues to open can drive the fourth transmission gear 38 and the second rotating column 42 to rotate through the rack 39, so that the safety partition 4 is deflected toward the ladder opening 2, thereby preventing the ladder door 3 from interfering with the deflection of the safety partition 4 toward the ladder opening 2.

[0112] When the elevator door 3 is closed, the elevator door 3 will not drive the rack 39 to move synchronously at the beginning of its translation. During this period, the elevator door 3 will push the corresponding safety partition 4 to deflect in the opposite direction until the rack 39 is relatively located at one end in the slide groove. At this time, the elevator door 3 can drive the fourth transmission gear 38 to rotate through the rack 39, so that the fourth transmission gear 38 drives the corresponding safety partition to further deflect and return to the interior of the elevator car 1 through the second rotating column 42.
