Description

Technical Field

[0001] This invention belongs to the field of shaft construction technology, and particularly relates to a water-proof device for the cage of a shaft construction hoist and its assembly method. Background Technology

[0002] Construction elevators are a type of construction hoist. They consist of several parts, including a car (also called a hoist cage), a drive mechanism, standard sections, wall attachments, a chassis, railings, and an electrical system. They are commonly used construction machinery for carrying people and goods.

[0003] Most construction hoist cages on the market are currently constructed using integral welding. During the welding process, if the top weld is incomplete, the sealing cannot be guaranteed. Furthermore, in the unfinished elevator shaft, dripping or leaking water can occur. Therefore, in the complex and variable construction environment, incomplete welding of the hoist cage top can cause water seepage inside the cage. For example, deformation of the cage top plate weld can lead to severe water accumulation, often causing rust and perforation. If leakage occurs, it can also affect the normal operation of related electrical systems, requiring complete replacement. In short, this not only affects the service life of the steel structure, but short circuits in the electrical control system can also endanger the safety of passengers.

[0004] Currently, splicing is used to assemble the cage top instead of welding. This method typically uses screws or bolts for fixing. Because cage top structures vary in size, a large number of bolts are usually used. If the spliced ​​cage top leaks, each bolt needs to be inspected, resulting in a large workload and high maintenance costs. Reducing the number of bolts compromises the sealing requirements at the joints of the spliced ​​cage top. Furthermore, since drainage often occurs at the edges of the cage top, these edges are most prone to loosening and rusting. Therefore, improving the sealing performance of the spliced ​​cage top while reducing maintenance costs is a pressing issue that needs to be addressed. Summary of the Invention

[0005] The purpose of this invention is to provide a water-proof device for a hoist cage in a construction hoist and its assembly method. This invention allows for adjustment of the hoist cage's size to meet the needs of various locations. By increasing or decreasing the number of waterproof adjustment structures, the length of the cage structure can be varied for easy adjustment. The water-proof device uses a bent plate with drainage channels, and the waterproof adjustment structures are assembled and connected using bolts. Water flows along both sides of the drainage channels to the ground, preventing leakage. A locking structure is included, which reduces the number of bolts used to fix the top of the cage while ensuring its airtightness. Furthermore, the reduced number of bolts allows for quick identification of problems during maintenance. To achieve the above objectives, this invention employs the following technical effects:

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the present invention, and these aspects of the invention can be implemented even without these specific details.

[0033] like Figure 1-4 As shown, a water-proof device for a hoist cage in a shaft construction hoist according to the present invention includes a main structure 1, which is generally plate-shaped and composed of several metal parts. The metal parts include a patterned plate 1-1. A horizontally placed grooved bent plate 1-2 is welded to the front end and the bottom of the middle section of the patterned plate 1-1. A grooved bent plate 1-2 perpendicular to the grooved bent plate 1-2 is welded to the rear end face of the grooved bent plate 1-2 at the bottom of the middle section of the patterned plate 1-1. The right-angled grooved bent plate 1-2 is arranged at the middle of the rear end of the grooved bent plate 1-2 at the bottom of the middle section of the patterned plate 1-1. A horizontally placed square tube 1-5 is welded to the bottom rear end of the patterned plate 1-1. The front end of the square tube 1-5 is welded to the rear end of the right-angled grooved bending plate 1-2. A C-shaped bending plate 1-4 is provided on the left and right sides of the patterned plate 1-1. Two horizontally placed square tubes 1-3 are welded longitudinally at equal intervals on the side of the bending plate 1-4 away from the patterned plate 1-1. Longitudinal square tubes 1-5 are welded to the side of the two square tubes 1-3 away from the bending plate 1-4. Ribs 1-6 for increasing strength are also welded on the grooved bending plate 1-2 and the bending plate 1-4.

[0034] The main structure 1 is bolted to the side with connectors. The connectors on both sides of the main structure 1 are several detachable waterproof adjustment structures 2 arranged in a horizontal sequence. The main body of the waterproof adjustment structure 2 is a metal plate. The right end of the waterproof adjustment structure 2 is bent downward and then bent to the left to form an arc-shaped flange 2-1. The left end of the waterproof adjustment structure 2 is bent downward, then bent to the left and then bent upward to form a drainage groove 2-2. The bottom of the front and rear ends of the waterproof adjustment structure 2 are respectively welded with rectangular tubes 6 to improve strength. The right and left ends of the waterproof adjustment structure 2 are provided with through holes, which are used to splice multiple waterproof adjustment structures 2 together and fix them together with bolts.

[0035] The left and right ends of the waterproof adjustment structure 2 on both sides are bolted to the second waterproof adjustment structure 3. The right end of the second waterproof adjustment structure 3 is bent downward and then bent to the left to form a bend 3-1. The left end of the second waterproof adjustment structure 3 is bent downward to form a side plate 3-2. Rectangular tubes 6 for improving strength are welded to the bottom of the front and rear ends of the second waterproof adjustment structure 3. The left end of the waterproof adjustment structure 2 and the right end of the second waterproof adjustment structure 3 are attached together and fixed by bolts.

[0036] A vertical rectangular groove is provided on the front end face of the rectangular tube 6 at the front end of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3. A vertical rectangular groove is also provided on the rear end face of the rectangular tube 6 at the rear end of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3. The rectangular groove is opened from the top of the rectangular tube 6, and the starting opening of the rectangular groove is milled into a semi-circle.

[0037] The locking structure includes a tensioning component 5 and a protective square tube 4. The tensioning component 5 includes a rectangular metal sheet 5-1 with a thickness of 2mm or more. A nut 5-2 is welded to the front end of the metal sheet 5-1. A through hole is provided on the metal sheet 5-1, which is coaxial with the screw hole of the nut 5-2. A locking screw 5-5 is screwed into the nut 5-2. The locking screw 5-5 can be replaced by a large bolt. The threaded end of the locking screw 5-5 rests on the front end face of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3. A groove can be provided on the front end face of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3 to accommodate the threaded end of the locking screw 5-5, thus preventing the locking screw 5-5 from swinging. The front end face of the metal sheet 5-1... Inclined through holes are provided on both the left and right sides, and metal rods 5-3 are provided in the inclined through holes. Metal rods 5-3 can be replaced by metal ropes or steel wire ropes. Limiting protrusions 5-4 are welded to both ends of the metal rods 5-3. In this embodiment, the limiting protrusions 5-4 are round blocks with a certain thickness. Of course, the shape of the limiting protrusions 5-4 is not limited to the one specified in this embodiment. The two metal rods 5-3 on the metal sheet 5-1 are located at one end relative to the metal sheet 5-1 in the rectangular grooves respectively provided in the waterproof adjustment structure 2 and the second waterproof adjustment structure 3. The limiting protrusions 5-4 at the front end of the metal rods 5-3 are attached to the front end face of the metal sheet 5-1 to form a limit. The limiting protrusions 5-4 at the rear end of the metal rods 5-3 are attached to the inner surface of the rectangular tube 6 to form a limit.

[0038] The protective square tube 4 is a long strip of square tube with a relief groove on its end face. The protective square tube 4 covers the tensioning member 5 through the relief groove and is bolted to the main structure 1, the waterproof adjustment structure 2 and the second waterproof adjustment structure 3.

[0039] like Figure 4As shown, the principle of the tensioning component 5 is as follows: when the locking screw 5-5 is tightened, the threaded end of the locking screw 5-5 will press against the front end face of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3, forming a tightening force F1. As the locking screw 5-5 rotates, the metal plate 5-1 and the nut 5-2 move in the opposite direction of the tightening force F1. The metal plate 5-1 drives the two metal rods 5-3 to move. Since the metal rods 5-3 are arranged at an angle, when the two metal rods 5-3 move, they will generate a pulling force F2 in the opposite direction of the tightening force F1. The two pulling forces F2 form a resultant force, which tightens the front end of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3. The rear end of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3 are also tightened in the same way as described above.

[0040] It is worth noting that in this embodiment, a tensioning member 5 is also arranged at the connection between the main structure 1 and the waterproof adjustment structure 2, such as... Figure 3 As shown, a groove needs to be milled on the front end face of the square tube 1-3, and a round hole larger than the limiting protrusion 5-4 needs to be drilled so that the metal rod 5-3 and the limiting protrusion 5-4 at the rear end can be placed inside the square tube 1-3; the center of these tensioning parts 5 are fixed at the front end face of the contact surface of each structure, because the strength at this point is high and can meet the tightening force of the locking bolt 5-5.

[0041] The waterproof adjustment structure 2 on the right side and the waterproof adjustment structure 2 on the left side of the main structure 1 are arranged in opposite directions; the second waterproof adjustment structure 3 on the right side of the main structure 1 and the locking knot 2 on the left side are arranged in opposite directions; a sealing layer is also provided between the main structure 1 and the waterproof adjustment structure 2, between the waterproof adjustment structure 2 and the waterproof adjustment structure 2, and between the waterproof adjustment structure 2 and the second waterproof adjustment structure 3, and the sealing layer is glue or sealant.

[0042] The main structure 1, the waterproof adjustment structure 2, and the second waterproof adjustment structure 3 are each welded together to form a whole by high-strength bolts. If the size of the waterproof device needs to be adjusted, the number of waterproof adjustment structures 2 and second waterproof adjustment structures 3 can be increased or decreased on both the left and right sides at the same time. When water drips onto the device, the water flows out along the drainage channel 2-2 of the waterproof adjustment structure 2 and is discharged to the ground.

[0043] This embodiment also provides a method for assembling a water-proof device for a hoist cage in a shaft construction hoist, the steps of which are as follows:

[0044] Step 1: Assemble the main structure 1, the waterproof adjustment structure 2, and the second waterproof adjustment structure 3;

[0045] Step 2: Install the tensioning component 5. Place the ends of the metal rods 5-3 on both sides of the tensioning component 5 into the rectangular grooves of the rectangular tubes 6 at the front end of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3, respectively. Then tighten the locking screws 5-5. When the locking screws 5-5 are engaged with the front end surfaces of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3, continue to tighten the locking screws 5-5 until they are fully engaged. At this point, the two metal rods 5-3 will tighten the edges of the waterproof adjustment structure 2 and the second waterproof adjustment structure 3 through the limiting protrusions 5-4 at their front and rear ends.

[0046] Step 3: Install the protective square tube 4. Put the protective square tube 4 onto the locking part and tighten the bolts.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
