Description

Technical Field

[0001] This utility model belongs to the field of elevator installation technology and relates to a transfer device for elevator installation. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving on at least two rigid tracks perpendicular to the horizontal plane or at an angle of less than 15° to the vertical. During elevator installation, because elevator door panels are typically large, heavy, and easily scratched, a transfer device is needed to move the elevator door panels.

[0003] A transfer device for elevator installation disclosed in Chinese patent CN215851385U includes a base with multiple sliding grooves on both sides; multiple supports distributed linearly and equally spaced are tightly welded to the top surface of the base; the base is also provided with an anti-slip mechanism, which includes two symmetrical movable seats, multiple sliders are tightly welded to the top surface of the movable seats, the sliders are slidably connected to the corresponding sliding grooves, and baffles are tightly welded to the top surface of each slider, with clamping grooves on the inner sidewalls of the baffles.

[0004] The transfer device uses a moving baffle to hold the end of the elevator door in the clamping groove. Since the elevator door is placed directly between two adjacent supports, the baffle only restricts the elevator door in the horizontal direction and does not restrict it in the vertical direction, which makes it risky for the elevator door to move upward during the transfer process.

[0005] To solve the above problems, this utility model proposes a transfer device for elevator installation. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a transfer device for elevator installation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a base plate, and a plurality of first partitions are fixedly connected at intervals in the middle of the top surface of the base plate. Clamping members are horizontally slidably arranged at both ends of the base plate, and the plurality of first partitions are located between two clamping members.

[0008] Two connecting rods are rotatably provided on both sides of the two ends of the base plate. Each clamping member is hinged to the two corresponding connecting rods with a spring. A pressure rod is fixedly connected to the top of the two connecting rods located at the same end of the base plate.

[0009] A drive assembly is provided at the bottom of the base plate, which drives the two pressure rods to rotate in opposite directions or in opposite directions.

[0010] Furthermore, the clamping member includes clamping plates, and a number of second partitions are fixedly connected at intervals on the side of the two clamping plates that are close to each other. The number of second partitions on the two clamping plates is equal to the number of first partitions and corresponds one-to-one.

[0011] Furthermore, each of the two sides of the two ends of the top surface of the base plate is provided with a sliding groove, and each of the two ends of the bottom surface of each clamping plate is fixedly connected with a slider, and the two sliders are respectively limited and slidably connected in the corresponding two sliding grooves.

[0012] Furthermore, each of the two sides at both ends of the base plate is fixedly connected to a fixed shaft, and the connecting rod is rotatably sleeved on the corresponding fixed shaft, with the bottom end of the connecting rod located below the base plate.

[0013] Furthermore, each of the clamping plates is provided with a spring at both ends, and a second connecting shaft is fixedly connected to the side of the two second partitions located at the two ends of the clamping plates that are far apart from each other. A second rotating seat is fixedly connected to the bottom end of each spring, and the second rotating seat is rotatably sleeved on the corresponding second connecting shaft.

[0014] Two connecting rods located at the same end of the base plate are fixedly connected to a first connecting shaft on their adjacent sides. Each spring is fixedly connected to a first rotating seat at its top end. The first rotating seat is rotatably sleeved on the corresponding first connecting shaft.

[0015] Furthermore, a crossbar is fixedly connected to the bottom end between the two connecting rods located at the same end of the base plate.

[0016] Furthermore, the drive assembly includes a lead screw, a limiting groove is formed on the bottom surface of the base plate, the lead screw is rotatably connected to the inside of the limiting groove, a motor is fixedly installed at one end of the base plate at the end of the limiting groove, and one end of the lead screw is rotatably connected to the output end of the motor after passing through the end face of the limiting groove.

[0017] The lead screw is provided with two threaded sections with opposite directions of rotation. Each threaded section is threaded with a sliding bracket, and the top of each sliding bracket is slidably connected to the inside of the limiting groove.

[0018] Both of the sliding frames are provided with vertical slots, and the two crossbars slide vertically through the two vertical slots respectively.

[0019] Furthermore, a handrail is fixedly installed at one end of the top surface of the base plate, and wheels are installed at the four corners of the bottom surface of the base plate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The elevator installation transfer device is equipped with a pressure rod. When the lead screw drives the two sliding frames to move away from each other, the sliding frames push the crossbar on them to move, so that the crossbar slides inside the sliding frame and pulls the connecting rod to rotate, causing the pressure rod to rotate. This allows the pressure rod to abut against the top of the elevator door panel at the first partition, thereby limiting the elevator door panel to the top of the base plate. This provides a good limiting effect on the elevator door panel and reduces the risk of the elevator door panel moving up during the transfer process.

[0022] 2. The elevator installation transfer device is equipped with a spring, which is hinged between the connecting rod and the clamping plate. When the connecting rod rotates and the pressure rod abuts against the top of the elevator door panel, the connecting rod will pull the clamping plate to move through the spring, so that the clamping plate abuts against the end of the elevator door panel. Thus, by rotating the connecting rod, the elevator door panel can be restricted in different directions, which is easy to operate. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-5As shown, the technical solution adopted by this utility model is as follows: A transfer device for elevator installation includes a base plate 1, and a plurality of first partitions 2 are fixedly connected at intervals in the middle of the top surface of the base plate 1. Rubber pads are provided on the adjacent sides of two adjacent first partitions 2, so that the elevator door panel is positioned between two adjacent first partitions 2, which has a protective function for the elevator door panel.

[0031] Both ends of the base plate 1 are horizontally slidably equipped with clamping members, and several first partitions 2 are located between two clamping members. This allows the two clamping members to clamp the two ends of the elevator door panel respectively.

[0032] The clamping component includes clamping plates 5, which are slidably connected to the top of the base plate 1. Several second partitions 6 are fixedly connected at intervals on the adjacent sides of the two clamping plates 5. The number of second partitions 6 on the two clamping plates 5 is equal to and corresponds one-to-one with the number of first partitions 2. When the clamping plates 5 move to the end of the elevator door panel, two adjacent second partitions 6 are also located on both sides of the elevator door panel, limiting the end position of the elevator door panel.

[0033] Each of the two ends of the top surface of the base plate 1 has a sliding groove 3 on each side. Each of the two ends of the bottom surface of each clamping plate 5 is fixedly connected to a slider 4, and the two sliders 4 are respectively limited and slidably connected in the corresponding two sliding grooves 3. The movement of the clamping plate 5 is positioned by the cooperation of the sliders 4 and the sliding grooves 3.

[0034] Connecting rods 8 are rotatably mounted on both sides of the two ends of the base plate 1.

[0035] Two fixed shafts 7 are fixedly connected to two sides at both ends of the base plate 1, and the connecting rod 8 is rotatably sleeved on the corresponding fixed shaft 7. The bottom end of the connecting rod 8 is located below the base plate 1, and the top end of the connecting rod 8 is located above the base plate 1.

[0036] Each clamping element is hinged to its corresponding two connecting rods 8 by a spring 12.

[0037] Each clamping plate 5 has a spring 12 at both ends. A second connecting shaft 14 is fixedly connected to the two second partition plates 6 located at the two ends of the clamping plate 5 on opposite sides, and the second connecting shaft 14 is horizontally arranged. A second rotating seat 13 is fixedly connected to the bottom end of each spring 12, and the second rotating seat 13 is rotatably sleeved on the corresponding second connecting shaft 14.

[0038] Two connecting rods 8 located at the same end of the base plate 1 are fixedly connected to a first connecting shaft 10 on their adjacent sides. The first connecting shaft 10 and the second connecting shaft 14 are parallel and correspond vertically. A first rotating seat 11 is fixedly connected to the top of each spring 12, and the first rotating seat 11 is rotatably sleeved on the corresponding first connecting shaft 10. This allows the connecting rod 8 to pull the clamping plate 5 to slide on the top of the base plate 1 through the spring 12 when it rotates. At the same time, the first rotating seat 11 and the second rotating seat 13 will rotate with the rotation of the connecting rod 8, thereby adjusting the angle of the spring 12.

[0039] A pressure rod 9 is fixedly connected to the top of the two connecting rods 8 located at the same end of the base plate 1. A crossbar 18 is fixedly connected to the bottom of the two connecting rods 8 located at the same end of the base plate 1. The connecting rod 8 connects the pressure rod 9 and the crossbar 18. When the crossbar 18 moves, it will push the pressure rod 9 to move through the connecting rod 8. Both the crossbar 18 and the connecting rod 8 are cylinders.

[0040] A drive assembly is provided at the bottom of the base plate 1, which drives the two pressure rods 9 to rotate in opposite directions or in opposite directions. The pressure rods 9 rotate around their corresponding fixed axes 7.

[0041] The drive assembly includes a lead screw 15. A limiting groove is formed on the bottom surface of the base plate 1, and the lead screw 15 is rotatably connected inside the limiting groove. A motor 16 is fixedly installed at one end of the base plate 1, located at the end of the limiting groove. One end of the lead screw 15 rotates through the end face of the limiting groove and is then fixedly connected to the output end of the motor 16. This allows the motor 16 to drive the lead screw 15 to rotate.

[0042] The lead screw 15 has two threaded sections with opposite directions of rotation, and each threaded section is threaded with a sliding bracket 17. The top ends of the two sliding brackets 17 are slidably connected to the inside of the limiting groove. The limiting groove limits the sliding brackets 17. When the lead screw 15 rotates, it drives the two sliding brackets 17 to move, and the two sliding brackets 17 move in opposite directions.

[0043] Both sliding frames 17 have vertical slots, and two crossbars 18 slide vertically through the two slots respectively. This allows the sliding frames 17 to move and push the crossbars 18 to move, enabling the crossbars 18 to slide within the vertical slots.

[0044] A handrail 20 is fixedly installed at one end of the top surface of the base plate 1. Wheels 19 are installed at the four corners of the bottom surface of the base plate 1.

[0045] Working principle:

[0046] During elevator installation, the elevator door panel to be transferred is placed between two adjacent first partitions 2. The elevator door panel will be located on top of the base plate 1 and between the two clamping plates 5, and below the pressure bar 9.

[0047] Start motor 16, and the output shaft of motor 16 rotates forward. This drives lead screw 15 to rotate. Lead screw 15 drives two sliding frames 17 to move away from each other, so that the sliding frames 17 slide within the limiting groove on the bottom surface of base plate 1.

[0048] When the sliding frame 17 moves, it pushes the crossbar 18, causing the crossbar 18 to slide within the sliding frame 17. The movement of the crossbar 18 causes the connecting rod 8 to rotate, causing the pressure rod 9 to rotate around the fixed axis 7. The pressure rod 9 then moves towards the top of the elevator door panel.

[0049] Simultaneously, when the connecting rod 8 rotates, it drives the first connecting shaft 10 to move. The first connecting shaft 10 pulls one end of the spring 12 through the first rotating seat 11. The other end of the spring 12 pulls the second connecting shaft 14 to move through the second rotating seat 13, thereby moving the second partition 6 and the clamping plate 5. At the same time, the first rotating seat 11 rotates on the first connecting shaft 10, and the second rotating seat 13 rotates on the second connecting shaft 14.

[0050] The spring 12 pulls the clamping plate 5 to slide on the top surface of the base plate 1, bringing the two clamping plates 5 closer together. The slider 4 slides inside the slide groove 3 to position the clamping plate 5. This causes the clamping plate 5 to move towards the end of the elevator door panel, and the second partition 6 to move towards the side of the end of the elevator door panel.

[0051] The clamping plate 5 will first move to the end of the elevator door panel. Then the pressure rod 9 continues to rotate downwards until it abuts against the top of the elevator door panel. At this time, the connecting rod 8 will continue to pull the clamping plate 5 to move through the spring 12. Since the clamping plate 5 no longer moves, the connecting rod 8 will stretch the spring 12, and the spring 12 will exert a pulling force on the clamping plate 5, so that the clamping plate 5 abuts against the elevator door panel.

[0052] Rubber pads can also be placed on the clamping surfaces of the clamping plate 5 and the second partition plate 6.

[0053] Then, the elevator door panel is fixed in different positions by the cooperation of the clamping plate 5 and the pressure rod 9. After that, the handrail 20 is pushed, and the base plate 1 can be moved by the wheels 19, so that the elevator door panel can be moved and transported.

[0054] When the elevator door panel needs to be removed, motor 16 is started, and the output shaft of motor 16 reverses. The lead screw 15 rotates, thereby driving the two sliding brackets 17 to move closer to each other. Similarly, the sliding brackets 17 push the crossbar 18, causing the connecting rod 8 and the pressure rod 9 to rotate. The pressure rod 9 will then move away from the top of the elevator door panel.

[0055] Link 8 pulls one end of spring 12 to move. Since spring 12 is in a stretched state, it will continue to pull clamp 5 against the end of the elevator door panel. Afterwards, spring 12 gradually returns to its original state, and spring 12 will pull clamp 5 and second partition 6 away from the elevator door panel.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
