Description

Technical Field

[0001] The utility model provides a safety locking device for a construction elevator and belongs to the technical field of construction elevators. Background Art

[0002] Construction hoists are vertical lifting and transportation equipment widely used in construction. Construction hoists are generally composed of three parts: a main column, a cage and a transmission mechanism. The main column is composed of several standard section steel frames, and the cage is a rectangular frame cage formed by welding steel structures; the transmission mechanism is formed by a combination of a motor, a reducer and an output gear; the transmission mechanism and the cage are both equipped with guide wheels coupled with the standard section; the transmission mechanism is connected to the cage through two dumplings. When the transmission mechanism is working, the output gear is driven to move relative to the rack installed on the standard section, driving the cage to move up and down along the standard section, thereby realizing vertical transportation operations. Among them, the cage of the construction hoist is generally equipped with a discharge cage door.

[0003] In order to facilitate the entry and exit of goods, the existing unloading cage door is generally divided into an upper door panel and a lower door panel. The upper door panel of the cage is manually operated to descend and the lower door panel is reversely raised until the bottom wall of the upper door panel is tightly fitted with the top wall of the lower door panel. When the upper door panel and the lower door panel are combined, a buckle is usually hinged at the bottom of the upper door panel side wall, and the lower end of the buckle buckles the lower door panel side wall, so that the upper door panel and the lower door panel are locked together to prevent separation. However, since the buckle is relatively loose, it is inevitable that the upper door panel and the lower door panel that were originally closed together on the cage will be separated due to machine failure, materials or human accidental collision, which will cause the upper door panel and the lower door panel of the cage door to separate and open, which has certain safety hazards. Based on this, the utility model provides a construction hoist safety locking device. Utility Model Content

[0004] The technical problem solved by the utility model is: a live buckle is hinged at the bottom of the side wall of the upper door panel to buckle the lower door panel, but because the live buckle is relatively loose, it is inevitable that the upper door panel and the lower door panel will be separated due to factors such as machine failure, materials or human accidental contact, which poses certain safety hazards.

[0005] In order to solve the technical problem, the utility model provides a technical solution: a construction elevator safety locking device, comprising an upper door panel and a lower door panel, a support block is provided at the bottom of the side wall of the upper door panel, locking rods are symmetrically provided at the four corners of the bottom of the support block, and a locking assembly for locking the locking rod is provided at the top of the side wall of the lower door panel, the locking assembly comprises a hollow block, a slide plate is slidably connected to the hollow block, insertion rods passing through the locking rods are symmetrically provided on both sides of one side wall of the slide plate, a screw rod threadedly connected to the side wall of the hollow block is rotatably connected to the other side wall of the slide plate, and a handle is provided at the other end of the screw rod.

[0006] Furthermore, the end of the screw rod is rotatably connected to the side wall of the slide plate via a bearing.

[0007] Furthermore, two inner side walls of the hollow block are symmetrically provided with slide rails matching the side walls of the slide plate.

[0008] Furthermore, the upper and lower side walls of the hollow block are provided with insertion holes matching the locking rod.

[0009] Furthermore, a locking hole matching the insertion rod is provided on the rod body of the locking rod.

[0010] Beneficial effects of the utility model:

[0011] By fully inserting the insertion rod into the locking hole on the locking rod, the position of the locking rod can be locked and fixed. When the cage on the construction elevator is raised and lowered, the upper door panel and the lower door panel that were originally closed together on the cage are separated due to machine failure, materials or human accidental collision, the locking rod can be locked and fixed through the insertion rod, effectively preventing the upper door panel and the lower door panel from separating, effectively reducing safety hazards.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] According to the attached Figure 1 , 2, 3, and 5: The utility model provides a safety locking device for a construction elevator: it includes an upper door panel 1 and a lower door panel 2. A support block 3 is provided at the bottom of the side wall of the upper door panel 1. Locking rods 4 are symmetrically provided at the four corners of the bottom of the support block 3. A locking assembly 5 for locking the locking rod 4 is provided at the top of the side wall of the lower door panel 2. The locking assembly 5 includes a hollow block 6. A slide plate 7 is slidably connected in the hollow block 6. Insertion rods 8 that pass through the locking rod 4 are symmetrically provided on both sides of one side wall of the slide plate 7. A screw threadedly connected to the side wall of the hollow block 6 is rotatably connected to the other side wall of the slide plate 7. Rod 9, the other end of the screw rod 9 is provided with a handle 10 placed on the outside of the hollow block 6, and the position of the locking rod 4 can be locked and fixed by fully inserting the insertion rod 8 into the locking hole 14 on the locking rod 4. When the cage on the construction elevator is lifted up and down, the upper door panel 1 and the lower door panel 2 that were originally closed together on the cage are separated due to machine failure, materials or human accidental collision, the locking rod 4 can be locked and fixed by the insertion rod 4, effectively preventing the upper door panel 1 and the lower door panel 2 from separating, and effectively reducing safety hazards.

[0020] According to the attached Figure 5 As shown: the end of the screw rod 9 is rotatably connected to the side wall of the slide plate 7 via a bearing 11, thereby ensuring that the screw rod 9 can effectively rotate.

[0021] According to the attached Figure 5 As shown: the two inner side walls of the hollow block 6 are symmetrically provided with slide rails 12 that match the side walls of the slide plate 7, which play a role in limiting the position of the slide plate 7.

[0022] According to the attached Figure 4 , 5 As shown, both the upper and lower side walls of the hollow block 6 are provided with insertion holes 13 matching with the locking rod 4 , so that the locking rod 4 can pass through the hollow block 6 through the insertion holes 13 .

[0024] Principle of the utility model

[0025] When in use, after the material loading and unloading is completed, the upper door panel 1 of the cage is manually operated to descend and the lower door panel 2 is raised in the opposite direction until the bottom wall of the upper door panel 1 is tightly fitted with the top wall of the lower door panel 2. At this time, the locking rod 4 passes through the hollow block 6 through the insertion hole 13, and the insertion rod 8 is connected with the locking hole 4. The staff holds the handle 10 and rotates it, driving the screw 9 to rotate and move in the direction close to the locking rod 4, thereby driving the slide plate 7 and the insertion rod 8 to move in the direction close to the locking rod 4 until the insertion rod 8 is fully inserted into the locking hole 14 on the locking rod 4, so that the position of the locking rod 4 can be locked and fixed. When the cage on the construction elevator is lifted up and down, the upper door panel 1 and the lower door panel 2 that were originally closed together on the cage are separated due to machine failure, materials or human accidental collision, the locking rod 4 can be locked and fixed by the insertion rod 4, effectively preventing the upper door panel 1 and the lower door panel 2 from separating, and effectively reducing safety hazards.
