Description

Technical Field

[0001] This utility model relates to the technical field of hoist cage equipment, specifically a vertical sliding door for a traction hoist cage in shaft construction. Background Technology

[0002] Vertical sliding doors for hoist cages can close the front of the cage during vertical movement, thereby improving the safety of equipment and personnel inside the cage.

[0003] Currently, most hoist cage doors in the market use horizontal sliding doors. When mortar transport vehicles enter and exit the cage, they drip into the horizontal sliding door track groove, which dries and causes door opening failure. Every time the transport vehicle enters or exits the cage, the wheels will contact the horizontal sliding door track, which is prone to deformation. Therefore, there is an urgent need for a vertical sliding door for traction hoist cages to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical sliding door for the cage of a traction shaft construction hoist, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical sliding door for a traction shaft construction hoist cage, comprising two sets of guide rails for mutual fixation and support, a fixed pulley guide seat provided at the top of the side end face of the two sets of guide rails, and a fixed pulley rotatably engaged at the outer end face of the fixed pulley guide seat; a door panel limiting baffle provided at the side end face of the guide rail near the fixed pulley.

[0006] An upper closing device is slidably disposed on the top of the guide rail and is used to close the front of the cage;

[0007] A lower closing device is slidably disposed at the bottom of the guide rail, and the lower closing device is used to close the front of the cage;

[0008] A steel wire rope, one end of which is fixedly connected to the upper closing device, and the other end of which is fixedly connected to the lower closing device.

[0009] Preferably, the lower closing device includes a lower door panel, with first guide rollers symmetrically arranged on the upper part of the side end face of the lower door panel, and first wire rope locking seats symmetrically arranged near the middle of the side end face of the lower door panel.

[0010] Preferably, the upper closing device includes an upper door panel, with second guide rollers symmetrically arranged on the side end face of the upper door panel near the center, and a second wire rope locking seat located on the side end face of the upper door panel near the lower part.

[0011] Preferably, a limiting baffle is provided at the rear of the upper door panel, and an alignment guide plate is provided at the rear of the lower door panel. The limiting baffle and the alignment guide plate are directly opposite each other. After the lower door panel and the upper door panel are closed, the limiting baffle and the alignment guide plate can support each other to prevent the lower door panel and the upper door panel from having a rigid collision, which would affect the service life of the lower door panel and the upper door panel.

[0012] Preferably, the lower door panel is slidably engaged with the inner end face of the guide rail via the first guide rail roller, and the upper door panel is slidably engaged with the inner end face of the guide rail via the second guide roller, which can effectively improve the stability of the lower and upper door panels in vertical displacement outside the guide rail.

[0013] Preferably, the weight of the upper door panel is greater than the weight of the first guide rail roller. Both the first and second wire rope locking seats are fixedly connected to the wire rope. The weight of the upper door panel is greater than the weight of the first guide rail roller, so that when the upper door panel moves down to close the door or moves up to open the door, it can offset part of the weight of the first guide rail roller, thus improving the convenience of opening and closing the door.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The guide rail of this utility model adopts a vertical arrangement, which prevents the mortar inside the mortar transport vehicle from dripping onto the guide rail when it enters and exits the cage. At the same time, the drying will not affect the opening and closing of the lower and upper door panels. In addition, the vertical arrangement can also guide the opening of the door with less effort through the gravity difference between the upper and lower door panels, thereby improving the convenience of opening the door.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a vertical sliding door for a traction shaft construction hoist cage, comprising two sets of guide rails 7 for mutual fixation and support. Fixed pulley guide seats 6 are provided at the top of the side end faces of the two sets of guide rails 7, and fixed pulleys 5 are rotatably engaged on the outer end faces of the fixed pulley guide seats 6. A door panel limiting baffle 3 is provided on the side end face of the guide rails 7 near the fixed pulleys 5.

[0023] The upper closing device 4 is slidably mounted on the top of the guide rail 7 and is used to close the front of the cage.

[0024] The lower closing device 2 is slidably disposed at the bottom of the guide rail 7 and is used to close the front of the cage.

[0025] Wire rope 1, one end of which is fixedly connected to the upper closing device 4, and the other end of which is fixedly connected to the lower closing device 2.

[0026] The lower closing device 2 includes a lower door panel 22. A first guide rail roller 21 is symmetrically arranged on the upper part of the side end face of the lower door panel 22, and a first wire rope locking seat 23 is symmetrically arranged near the middle of the side end face of the lower door panel 22.

[0027] The upper closing device 4 includes an upper door panel 41, with second guide rollers 42 symmetrically arranged on the side end face of the upper door panel 41 near the middle, and a second wire rope locking seat 43 located on the side end face of the upper door panel 41 near the lower part.

[0028] A limit baffle 8 is provided at the rear of the upper door panel 41, and an alignment guide plate 9 is provided at the rear of the lower door panel 22. The limit baffle 8 and the alignment guide plate 9 are directly opposite each other. After the lower door panel 22 and the upper door panel 41 are closed, the limit baffle 8 and the alignment guide plate 9 can support each other to prevent the lower door panel 22 and the upper door panel 41 from having a rigid collision, which would affect the service life of the lower door panel 22 and the upper door panel 41.

[0029] The lower door panel 22 is slidably engaged with the inner end face of the guide rail 7 via the first guide roller 21, and the upper door panel 41 is slidably engaged with the inner end face of the guide rail 7 via the second guide roller 42, which can effectively improve the stability of the lower door panel 22 and the upper door panel 41 in vertical displacement outside the guide rail 7.

[0030] The weight of the upper door panel 41 is greater than the weight of the first guide rail roller 21. The first wire rope locking seat 23 and the second wire rope locking seat 43 are both fixedly connected to the wire rope 1. The weight of the upper door panel 41 is greater than the weight of the first guide rail roller 21, so that when the upper door panel 41 moves down to close the door or moves up to open the door, it can offset part of the weight of the first guide rail roller 21, thus improving the convenience of opening and closing the door.

[0031] Working principle: When in use, if it is necessary to open the lower door panel 22 and the upper door panel 41 at the front of the cage to allow the mortar transport vehicle to exit, the operator can activate the external power module. The external power module can then lift the upper door panel 41. When the upper door panel 41 is lifted, it releases the tension limit on the wire rope 1, allowing the lower door panel 22 to move down along the guide rail 7 until the lower door panel 22 and the upper door panel 41 are fully open. At the same time, the guide rail 7 is arranged vertically, so when the mortar transport vehicle enters or exits the cage, it will not drip onto the guide rail 7, and drying will not affect the opening of the door, thus improving the stability of subsequent door opening.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
