Description

Technical Field

[0001] The present application relates to the technical field of elevator accessories, and in particular to a positioning device for connecting a stacker with an elevator. Background Art

[0002] In the prefabricated building industry, composite floor slabs are needed in production and processing. The traditional storage method is to store them on the ground, and the transportation method is to use a crane or a truck for transportation. This storage method and transportation method are inefficient, have a low level of automation, and cause great waste.

[0003] Therefore, the industry has established three-dimensional warehouses for storage, and used equipment such as stackers and elevators for transportation. The stackers are used to move and stack pallets with composite floor slabs inside the floors, and the elevators are used to transport the composite floor slabs between different floors.

[0004] However, during the lifting process of the elevator, due to mechanical vibration, the composite floor slab set on the elevator will produce a certain displacement relative to the elevator. After the position of the composite floor slab on the elevator changes, the position of the composite floor slab moved to the stacker will also change, thereby affecting the subsequent transportation of the composite floor slab by the stacker.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In order to prevent the pallet from being displaced relative to the elevator when the elevator moves, the present application provides a positioning device for connecting a stacker and an elevator.

[0007] The present application provides a positioning device for connecting a stacker and an elevator, which adopts the following technical solution:

[0008] A positioning device for connecting a stacker and an elevator, comprising:

[0009] A limiting member, the limiting member is movably connected to the elevator to prevent the pallet from moving;

[0010] A driving member, wherein the driving member is disposed on the limiting member and is used to drive the limiting member to move to a state where the movement of the tray is blocked;

[0011] and a reset member, wherein the reset member is used to drive the limiting member to move to a state of being separated from the tray;

[0012] The limiting member can abut against an end surface of the tray that is perpendicular to the sliding direction of the tray.

[0013] By adopting the above technical solution, after the pallet moves onto the elevator, the limiter moves to the moving path of the pallet, thereby hindering the movement of the pallet relative to the elevator, making it difficult for the pallet to be displaced relative to the elevator when the elevator moves, and making it difficult for the subsequent stacker to be affected by the movement of the pallet.

[0014] Optionally: a mounting seat is provided on the limit member, the mounting seat is provided on the elevator, the limit member is rotatably connected to the mounting seat, and one end of the limit member rotates upward and can abut against the end surface of the pallet perpendicular to its sliding direction.

[0015] By adopting the above technical solution, after the pallet is moved onto the elevator, the limiting member can be rotated to make the limiting member abut against the end of the pallet, making the limiting process of the pallet more convenient.

[0016] Optionally: the driving member is arranged at the end of the limiting member away from the tray, and the overall weight of the driving member and the limiting member at the end of the rotating shaft of the limiting member close to the driving member is greater than the overall weight of the limiting member at the end of the rotating shaft of the limiting member close to the tray.

[0017] By adopting the above technical solution, when not affected by external force, the limit member can maintain a vertical state under the downward gravity applied by the driving member, thereby stably limiting the movement of the pallet relative to the elevator.

[0018] Optionally: a weight-increasing portion is provided on both side walls of the limiting member which are located at a position of the limiting member's rotation axis close to the driving member and perpendicular to the rotation direction of the limiting member.

[0019] By adopting the above technical solution, the width of the limiter is increased to shorten the overall length of the limiter, so that the limiter can maintain a vertical state by relying on gravity, reducing the space occupied by the limiter, making the installation of the entire positioning device more convenient.

[0020] Optionally: the driving member is arranged on a side of the limiting member close to the mounting seat.

[0021] By adopting the above technical solution, the driving member is unlikely to come into contact with the resetting member when moving with the limiting member, and the driving member is unlikely to hinder the rotation of the limiting member.

[0022] Optionally: a reset slope is provided on the side wall of the reset member perpendicular to the moving direction of the elevator, and one end of the reset slope is parallel to the rotation axis of the limit member and tilted downward. A connecting member is provided on the limit member, and the connecting member can abut against the reset slope and slide along the reset slope. The connecting member is arranged on the side of the rotating shaft of the limit member close to the driving member.

[0023] By adopting the above technical solution, when the elevator moves to the loading or unloading position, the connecting piece on the limit member can contact the reset member and move along the reset inclined surface, thereby mobilizing the limit member to rotate, so that the limit member no longer blocks the movement of the pallet, allowing the pallet to move normally.

[0024] Optionally: a rolling member is provided on the connecting member, the rolling member is rotatably connected to the connecting member, and the rolling member can abut against the reset inclined surface and roll.

[0025] By adopting the above technical solution, the sliding fit between the connecting member and the reset inclined surface is transformed into a rolling fit by using a rolling member, thereby reducing the friction between the connecting member and the reset inclined surface and making the rotation of the limit member smoother.

[0026] Optionally, the shortest distance between the rolling element and the rotation axis of the limiting element is greater than the shortest distance between the vertical surface where the downwardly inclined end of the reset slope of the reset element is located and the rotation axis of the limiting element.

[0027] By adopting the above technical solution, when the rolling member moves along the side wall of the reset member, the limiting member can maintain an inclined state, so that the movement of the rolling member and the reset member is smoother.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Use the limiter to block the movement of the pallet, so that the pallet is not easy to move relative to the elevator during the movement of the elevator, and the pallet is not easily affected by the subsequent movement of the stacker;

[0030] 2. Use the reset part to guide the rotation direction of the limit part. When the elevator moves into place, the reset part can contact the limit part to automatically drive the limit part to rotate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] The present application discloses a positioning device for connecting a stacker and a hoist, such as Figure 1 and Figure 2 As shown, it includes a limiting member 1 for blocking the movement of the pallet, a driving member 2 for driving the limiting member 1 to change to a state of blocking the movement of the pallet, and a reset member 3 for driving the limiting member 1 to change to a state of being separated from the pallet. The limiting member 1 is provided with a mounting seat 6 for defining its installation position, and the mounting seat 6 is installed on the hoist by bolts, and the mounting seat 6 can be respectively arranged at both ends of the moving direction of the pallet and located below the pallet.

[0038] like Figure 3 As shown, the limit member 1 is rotatably connected to the end of the mounting seat 6 away from the elevator. The limit member 1 is connected to the mounting seat 6 through a connecting component 4. The connecting component 4 includes an arm shaft 41 passed through the limit member 1, a self-lubricating copper sleeve 42 sleeved on the wall shaft, a flat washer 43, a spring washer 44 and a nut 45 threadedly connected to the arm shaft 41. The self-lubricating copper sleeve 42 and the head of the arm shaft 41 are arranged on the side of the mounting seat 6 away from the elevator, the flat washer 43, the spring washer 44 and the nut 45 are arranged on the side of the mounting seat 6 close to the elevator, the flat washer 43 abuts against the mounting seat 6, and the limit member 1 is sleeved on the self-lubricating copper sleeve 42 and rotatably.

[0039] like Figure 2 As shown, in this embodiment, the driving member 2 uses a counterweight block, and the driving member 2 is installed on the side wall of the limiting member 1 close to the mounting seat 6, and the driving member 2 is arranged at a position where the limiting member 1 is far away from the pallet. The overall weight of the driving member 2 and the limiting member 1 located at the end of the rotating shaft of the limiting member 1 close to the driving member 2 is greater than the overall weight of the limiting member 1 located at the end of the rotating shaft of the limiting member 1 close to the pallet, so that the limiting member 1 can maintain a vertical state when it is not subjected to external force, so that the limiting member 1 can abut against the end surface of the pallet to limit the position of the pallet on the elevator, so that the pallet is not easy to move relative to the elevator during the operation of the elevator.

[0040] A weight-added portion 11 is integrally formed on both side walls of the limit member 1 at a position where its rotation axis is close to the driving member 2 and perpendicular to the rotation direction of the limit member 1. The weight-added portions 11 on both sides of the limit member 1 are the same in size, and the length of the limit member 1 on the side close to the weight-added portion 11 on the rotation axis is shorter than the length on the side away from the weight-added portion 11, thereby shortening the overall length of the limit member 1 and making the space required for the entire structure smaller.

[0041] like Figure 1 As shown, the reset member 3 is arranged at both ends of the position where the elevator stops according to the stop position of the elevator. The reset member 3 is respectively arranged on the upper and lower end faces of the tray on the elevator. The side walls of the reset member 3 facing the approaching direction of the elevator are all provided with reset slopes 31. The reset slope 31 is parallel to one end of the rotation axis of the limiter 1 and tilts downward. A connecting member 12 is arranged on the side wall of the limiter 1 away from the driving member 2. The connecting member 12 is arranged on the side of the rotation axis of the limiter 1 close to the driving member 2. In the process of the elevator moving from movement to stop, the connecting member 12 can abut against the reset slope 31 and move along the reset slope 31, so that the end of the limiter 1 provided with the connecting rod moves toward the pallet, so that the end of the limiter 1 that was originally in contact with the pallet moves downward, and no longer hinders the movement of the pallet.

[0042] like Figure 1 and Figure 2 As shown, a rolling member 13 is also rotatably connected to the connecting member 12, and the rotation axis of the rolling member 13 is parallel to the rotation axis of the limiting member 1. The rolling member 13 can roll against the reset inclined surface 31, thereby converting the sliding friction between the connecting member 12 and the reset member 3 into rolling friction, thereby making the rotation of the limiting member 1 smoother.

[0043] In order to make the rolling of the rolling member 13 on the reset member 3 smoother, the shortest distance between the rolling member 13 and the rotation axis of the limit member 1 is greater than the shortest distance between the vertical plane where the downwardly inclined end of the reset slope 31 of the reset member 3 is located and the rotation axis of the limit member 1, so that during the vertical movement of the limit member 1 along the reset member 3, the limit member 1 always remains in a tilted state, so that the movement of the limit member 1 is not easily affected.

[0044] like Figure 4 As shown, an elastic member 5 is provided on the side wall of the limiting member 1 close to the pallet, and a step surface 51 is provided on the side wall of the elastic member 5 close to the pallet at a position away from the rotation axis of the limiting member 1. The step surface 51 gradually moves away from the pallet as it moves away from the rotation axis of the limiting member 1. Therefore, after the overall length of the pallet changes, the adaptable surface on the step surface 51 can automatically abut against the pallet, thereby stably limiting the pallet.

[0045] The implementation principle of this embodiment is: when the elevator moves to the loading or unloading position, the rolling member 13 abuts against the reset slope 31 on the reset member 3, thereby driving the rolling member 13 to move, so that the limit member 1 rotates to the bottom of the pallet, so that the limit member 1 no longer hinders the movement of the pallet, and after the pallet is installed, the rolling member 13 disengages from the reset member 3 when the elevator moves, and the limit member 1 rotates under the action of the gravity applied by the driving member 2, so that the limit member 1 abuts against the pallet to limit the pallet.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
