[0001] The invention relates to a hoisting device, in particular to a guide rail hoisting device. Background Art

[0002] Traditional elevator installation uses scaffolding inside the shaft to install the elevator. The current market has switched to scaffold-free installation of elevators based on installation costs and installation cycles. When installing an elevator with a scaffold, the guide rail is hoisted using a U-shaped lifting ring to lock the installation hole of the guide rail connector and directly hoist it. After the guide rail is installed and fixed, the construction workers need to go to the top to unfasten the U-shaped lifting ring. When installing without a scaffold, if the U-shaped lifting ring is used to lock the guide rail connector for hoisting, when the guide rail is installed and fixed, the construction workers cannot climb up to unfasten the U-shaped bolts because there is no scaffold.

[0003] To this end, a lifting auxiliary device needs to be installed on the guide rail to loosen the U-bolt. The current lifting auxiliary device has two separable parts, so that it can be inserted into or removed from the guide rail in a separated state, and remain on the guide rail for lifting in a closed state. In addition, the spacing between the two separable parts is designed to be adjustable to match guide rails of different thicknesses. The two separable parts are fastened by a threaded connector after the spacing is adjusted, and the operation is cumbersome when separated. Summary of the invention

[0025] The embodiments of the present invention refer to Figure 1-4 , a guide rail hoisting device 100 is provided, including a seat body 110, a movable locking plate 120, an adjusting member 130 and a clamping member 140. A concave cavity 111 is provided on the seat body 110. The movable locking plate 120 is rotatably connected to the seat body 110 and is closed or separated from the seat body 110. When the seat body 110 and the movable locking plate 120 are closed, a gap 150 is formed between the two, and the gap 150 and the concave cavity 111 are connected to form a receiving cavity for the guide rail 200 to pass through. Specifically, the guide rail 200 includes a rail bottom 220 and a rail body 230, the rail body 230 is fixed on the rail bottom 220, the concave cavity 111 is for the rail body 230 to pass through, and the gap 150 is for the rail bottom 220 to pass through. The two ends of the adjusting member 130 are respectively connected to the seat body 110 and the movable locking plate 120, the movable locking plate 120 rotates around the adjusting member 130, and the movable locking plate 120 also moves forward and backward along the adjusting member 130 to adjust the width of the gap 150. The clamping member 140 is fixed on the base 110 and has an opening 141. The movable locking plate 120 has a clamping portion 121 and the opening 141 has an oblique edge 142 that matches the clamping portion 121. When the movable locking plate 120 and the base 110 are closed, the clamping portion 121 enters the opening 141 and clamps on the oblique edge 142.

[0026] When the guide rail hoisting device 100 is in use, the base 110 and the movable locking plate 120 are separated and inserted into the guide rail 200, and a guide rail connecting plate 210 is fixed on the top of the guide rail 200. The movable locking plate 120 rotates around the adjustment member 130 in a first direction and closes with the base 110, and the clamping portion 121 enters the opening 141 and clamps on the bevel 142, so that the movable locking plate 120 and the base 110 are closed by clamping. During hoisting, the guide rail hoisting device 100 is lifted by the lifting and hoisting equipment, and the guide rail hoisting device 100 rises along the guide rail 200 until it is clamped at the bottom of the guide rail connecting plate 210, and then it can be hoisted. After the guide rail 200 is fixed, the wire rope 310 of the lifting and hoisting equipment is loosened, and the guide rail hoisting device 100 slides downward under the action of gravity, and it can be released when it drops to the bottom of the guide rail 200. When removed and unlocked, the movable locking plate 120 rotates around the adjusting member 130 in the second direction and separates from the base body 110, and the second direction is the opposite direction of the first direction. For example, the first direction is clockwise and the second direction is counterclockwise, or the first direction is counterclockwise and the second direction is clockwise.

[0027] The guide rail lifting device 100 adopts a rotating separation and closing structure. Compared with the structure in the prior art in which both sides of the lifting auxiliary device are threadedly connected, the present invention is easy to operate and convenient for closing and separation. At the same time, since the movable locking plate 120 and the seat plate are threadedly connected, they need to be aligned during closed installation, while the present invention does not require alignment during closing.

[0028] Another embodiment of the present invention, referring to Figure 2 In order to match the guide rails 200 of different models (sizes), the bevel 142 of the guide rail hoisting device 100 is located on the side of the opening 141 close to the movable locking plate 120, and the other side opposite to the bevel 142 is a straight side 143, and the width of the opening 141 narrows from its entrance to its end. Since the position of the movable locking plate 120 will move forward and backward after adjusting the gap 150, the bevel 142 is used so that the clamping portion 121 can be clamped on the bevel 142 even if the front and rear positions of the movable locking plate 120 change.

[0029] Another embodiment of the present invention, referring to Figure 1 The clamping member 140 of the guide rail hoisting device 100 is convexly disposed on one side of the seat body 110 close to the movable locking plate 120, and the opening 141 is located on the rotation track of the clamping portion 121. Specifically, the clamping member 140 is a plate-shaped member, which is perpendicular to the second longitudinal plate 112, so that the clamping portion 121 can be better clamped.

[0030] Another embodiment of the present invention, referring to Figure 1The adjusting member 130 of the guide rail hoisting device 100 is a bolt, the head of the bolt is connected to the seat body 110, the root of the bolt passes through the movable locking plate 120 and the end thereof is screwed with a nut 131. The function of the nut 131 is to lock the movable locking plate 120 after the movable locking plate 120 moves forward and backward to complete the adjustment. Specifically, the movable locking plate 120 is provided with a hole position matched with the bolt, and the root of the bolt passes through the movable locking plate 120 through the hole position, and the movable locking plate 120 can move up and down and rotate along the bolt through the hole position.

[0031] Another embodiment of the present invention, referring to Figure 1 A gasket 132 is also sleeved on the bolt of the guide rail lifting device 100, and the gasket 132 is located between the nut 131 and the movable locking plate 120 to increase the pressure-bearing area.

[0032] Another embodiment of the present invention, referring to Figure 2 The movable locking plate 120 of the guide rail hoisting device 100 includes a first longitudinal plate 122 and a first transverse plate 123. The first transverse plate 123 is fixedly connected to the middle part of the upper side of the first longitudinal plate 122. The first transverse plate 123 is provided with a hoisting hole 124, and the hoisting direction of the hoisting hole 124 is upward. When the base 110 and the movable locking plate 120 are closed, the opening 141 faces downward. During hoisting, the U-shaped lifting ring 300 is inserted into the hoisting hole 124, and the steel wire rope 310 of the lifting equipment pulls up the U-shaped lifting ring 300. The movable locking plate 120 is subjected to an upward pulling force, so that it remains clamped in the opening 141 instead of being disengaged from the opening 141.

[0033] Further, refer to Figure 1 and Figure 2 The clamping portion 121 is the portion of the first longitudinal plate 122 that is clamped into the opening 141. The thickness of the clamping portion 121 should be smaller than the width of the opening 141 so as to be clamped into the opening 141.

[0034] Another embodiment of the present invention, referring to Figure 1 The base body 110 of the guide rail hanging device 100 includes a second longitudinal plate 112, a second transverse plate 113 and a third longitudinal plate 114. The left and right sides of the second transverse plate 113 are respectively fixedly connected to the upper side of the second longitudinal plate 112 and the upper side of the third longitudinal plate 114. A gap 150 is formed between the second longitudinal plate 112 and the movable locking plate 120. The adjusting member 130 and the clamping member 140 are respectively located on the left and right sides of the second longitudinal plate 112. The adjusting member 130 and the clamping member 140 respectively connect the movable locking plate 120 and the base body 110 from both sides, so that the guide rail hanging device 100 maintains a stable closed state.

[0035] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
