Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator parts processing technology, and in particular to an elevator parts cutting device. Background Technology
[0002] During the manufacturing, installation, and maintenance of elevators, some components may need to be cut according to actual needs. The car frame supports the car walls and floor, while the chassis components bear the weight of the car. When customizing the car dimensions (such as width), steel (such as steel plates) needs to be cut according to design requirements.
[0003] In existing technologies, steel plates are usually manually moved and placed under the cutter. After cutting, the steel plate is lifted out from under the cutter. This method poses a risk of worker injury from the cutter, such as accidental contact between the worker and the cutting end of the cutter, or the cutter falling and injuring the worker. It is quite dangerous. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides an elevator parts cutting device to solve the technical problems mentioned in the background art, such as the risk of workers accidentally coming into contact with the cutting end of the cutter, or the cutter falling and injuring workers.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] An elevator component cutting device includes two support plates, a cutting platform between the two support plates, and base plates that are vertically slidably mounted on opposite sides of the two support plates. The two base plates move synchronously on both sides of the cutting platform. Support plates that are slidably mounted along the length of opposite sides of the two base plates move synchronously and can extend beyond the end faces of the support plates. Positioning components are detachably mounted on both support plates. The two support plates are used to support the car steel plates to be cut, and the two sets of positioning components are used to lock the car steel plates to be cut on the support plates. A cutting component is mounted above the two support plates, and the cutting component is used to cut the car steel plates to be cut as they move downwards to the cutting platform along with the base plates.
[0007] Working principle:
[0008] In use, move the two bearing plates out of the end face of the support plate simultaneously, then place the car steel plate to be cut on the two bearing plates, and use the positioning components to fix the two sides of the bearing plates, and then move the bearing plates into the support plate.
[0009] Then, the two base plates are moved downwards synchronously, causing the steel plate of the car to be cut to move downwards to the cutting platform;
[0010] Finally, the cutting assembly is activated, and it cuts the car steel plate to be cut on the cutting platform.
[0011] Beneficial effects:
[0012] In this solution, by setting two synchronously movable bearing plates that extend out of the end face of the support plate, the position of the bearing plates can be changed, so that the bearing plates are far away from the cutting components. This allows workers to keep away from the cutting components when placing and removing the car steel plates to be cut, avoiding contact with the cutting components. By setting a positioning component, the car steel plates to be cut placed on the bearing plates can be locked, improving the stability of the cutting components during cutting.
[0013] By setting up two vertically movable base plates and a cutting platform, the two vertically movable base plates drive the car steel plate to be cut, which is placed on the support plate, to move downward to the cutting platform, so that the car steel plate to be cut comes into contact with the cutting platform, avoiding contact with the ground and thus avoiding damage to the ground. Attached Figure Description

[0015] Figure 2 for Figure 1 A schematic diagram of the structure for removing the cutting platform and the steel plate of the car to be cut;
[0016] Figure 3 for Figure 1 A top view of the structure after removing the cutting components.
[0017] In the above figures: support plate 1, cutting platform 2, base plate 3, bearing plate 4, connecting part 401, bearing part 402, motor 5, transmission shaft 6, moving block 7, roller 8, first electric telescopic rod 9, bottom plate 10, slide groove 11, contact part 1201, connecting part 1202, mounting part 1203, bolt 13, support rod 14, top plate 15, auxiliary block 16, second electric telescopic rod 17, cutter 18, car steel plate to be cut 19. Detailed Implementation
[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0019] Example:
[0020] like Figures 1-3As shown, an elevator parts cutting device includes two support plates 1, a cutting platform 2 between the two support plates 1, and base plates 3 vertically sliding on opposite sides of the two support plates 1. The two base plates 3 move synchronously on both sides of the cutting platform 2. Support plates 4 are slidably arranged along the length of opposite sides of the two base plates 3. The two support plates 4 move synchronously and can extend beyond the end face of the support plates 1. Positioning components are detachably installed on both support plates 4. The two support plates 4 are used to support the car steel plate 19 to be cut, and the two sets of positioning components are used to lock the car steel plate 19 to be cut on the support plates 4. A cutting component is installed above the two support plates 1. The cutting component is used to cut the car steel plate 19 to be cut as it moves downward with the base plates 3 onto the cutting platform 2.
[0021] In this solution, by setting two synchronously movable bearing plates 4 that extend out of the end face of the support plate 1, the position of the bearing plate 4 can be changed, so that the bearing plate 4 is away from the cutting component. This allows the worker to stay away from the cutting component when placing and removing the car steel plate 19 to be cut, thus avoiding contact with the cutting component. By setting a positioning component, the car steel plate 19 to be cut placed on the bearing plate 4 can be locked, improving the stability of the cutting component during cutting.
[0022] By setting two vertically movable base plates 3 and a cutting platform 2, the two vertically movable base plates 3 drive the car steel plate 19 to be cut, which is placed on the support plate 4, to move downward to the cutting platform 2, so that the car steel plate 19 to be cut comes into contact with the cutting platform 2, avoiding contact with the ground and damage to the ground.
[0023] like Figures 1-3 As shown, each substrate 3 has a motor 5 fixed at one end, and the output end of each motor 5 is connected to a transmission shaft 6 parallel to the length direction of the substrate 3. The other end of the transmission shaft 6 is connected to the corresponding substrate 3 through a bearing, and the outer wall of the bearing is fixed to the substrate 3. The transmission shaft 6 is a threaded rod, and each transmission shaft 6 is threadedly connected to a moving block 7. The side of each moving block 7 abuts against the side of the corresponding substrate 3. Two support plates 4 are set on the opposite sides of the two moving blocks 7. The two motors 5 are of the same specifications and operate synchronously to ensure that the two support plates 4 move synchronously. The bottom of each support plate 4 is connected to a moving support assembly, which is used to support the support plate 4 and move with it. The movement of the support plate 4 is realized by setting the motor 5, which is mechanized and automated and easy to operate; the moving support assembly can assist the movement of the support plate 4 and improve the stability of the support plate 4 during movement.
[0024] like Figure 2As shown, each of the movable support components includes a roller 8, a first electric telescopic rod 9, and a base plate 10. The roller 8 is located at the bottom of the base plate 10. The roller 8 is fixed to the base plate 10 by bolts or screws passing through the roller 8 bracket (or hub) and corresponding holes, and by nuts or threaded holes. The connection method of the roller 8 is prior art, and those skilled in the art should understand its structure, principle, and usage, etc., which will not be described in detail here. The roller 8 is used to support the rolling of the bearing plate 4 during movement and reduce friction. The fixed end of the first electric telescopic rod 9 is fixed to the top surface of the base plate 10, and the telescopic end of the first electric telescopic rod 9 is connected to the corresponding bearing plate 4. Both support plates 1 are provided with sliding grooves 11, and the two base plates 3 are vertically slidably disposed in the two sliding grooves 11. The sliding grooves 11 can limit the vertical movement of the base plates 3, improve the stability of the base plates 3 during vertical movement, and prevent displacement.
[0025] like Figures 1-3 As shown, the support plate 4 includes a connecting part 401 and a support part 402. The connecting part 401 is a vertical plate, and the support part 402 is a horizontal plate fixed to the bottom of the connecting part 401. The connecting part 401 of the support plate 4 is fixed to the moving block 7. The telescopic end of the first electric telescopic rod 9 is fixed to the bottom of the support part 402 of the support plate 4. Two first electric telescopic rods 9 are fixed to the bottom of the support part 402 of each support plate 4, and the two first electric telescopic rods 9 at the bottom of the support part 402 of the same support plate 4 are connected by the support of the support plate 4. The centrally symmetrical distribution of the parts 402 improves the load-bearing capacity of the bearing plate 4 and prevents the bearing plate 4 from tilting away from the moving block 7 due to the shift of the center of gravity after loading the car steel plate 19 to be cut. The four first electric telescopic rods 9 are all of the same specifications and operate synchronously to ensure that the two base plates 3 move synchronously. The car steel plate 19 to be cut is placed between the bearing parts 402 of the two bearing plates 4. The positioning component is detachably connected to the connecting part 401 of the bearing plate 4, which can adapt to fixing car steel plates 19 of different lengths to be cut, thus improving the practicality of the device.
[0026] like Figures 1-3As shown, each positioning component includes a contact portion 1201, a connecting portion 1202, and a mounting portion 1203. The contact portion 1201 is a mounting block parallel to the bearing portion 402 of the bearing plate 4. The connecting portion 1202 is a mounting block vertically fixed to the top of the contact portion 1201. The mounting portion 1203 is an "L"-shaped mounting block. One end of the mounting portion 1203 is fixedly connected to the top of the connecting portion 1202, and the other end of the mounting portion 1203 abuts against the side of the bearing plate 4 connecting portion 401 facing the support plate 1. A bolt 13 is threadedly connected to the other end of the mounting portion 1203. After the bolt 13 passes through the mounting portion 1203, it abuts against the side of the bearing plate 4 connecting portion 401 facing the corresponding base plate 3. This enables the disassembly and installation of the positioning components, and the operation is relatively simple.
[0027] like Figure 1 and Figure 2 As shown, two support rods 14 are provided on the opposite sides of the two support plates 1. A top plate 15 is fixed between the tops of the four support rods 14. A groove perpendicular to the length direction of the substrate 3 is provided at the bottom of the top plate 15. A slider is slidably disposed in the groove at the bottom of the top plate 15. A groove parallel to the length direction of the substrate 3 is provided at the bottom of the slider. An auxiliary block 16 is slidably disposed in the groove at the bottom of the slider. The above structure enables the auxiliary block 16 to move along the length and width direction of the substrate 3, thereby adapting to the cutting of steel plate materials of different specifications. Moreover, this movement method belongs to the prior art. Personnel should be familiar with its structure, principle, and usage, which will not be described in detail here. A second electric telescopic rod 17 is fixedly installed at the bottom of the auxiliary block 16, with its telescopic end facing downwards. The cutting assembly includes a cutter 18, which is a blade-type cutter. Its principle is to apply cutting force to the car steel plate 19 to be cut through the rapid reciprocating motion or rotation of a sharp blade. This cutter is existing technology, and those skilled in the art should be familiar with its structure, principle, and usage, which will not be described in detail here. The cutter 18 is fixedly installed at the telescopic end of the second electric telescopic rod 17. The movement of the telescopic end of the second electric telescopic rod 17 can change the vertical position of the cutter 18, thereby adapting to cutting car steel plates 19 of different thicknesses and improving the practicality of this device.
[0028] Working principle:
[0029] In use, the two motors 5 are started, and the output ends of the two motors 5 drive the corresponding transmission shafts 6 to rotate. The rotation of the two transmission shafts 6 drives the corresponding moving blocks 7 to move, so that the two bearing plates 4 move synchronously out of the end face of the support plate 1. Then, the car steel plate 19 to be cut is placed on the two bearing plates 4. Then, the worker puts the four contact parts 1201 against the top surface of the car steel plate 19 to be cut, and uses bolts 13 to screw into the mounting part 1203 and the connecting part 401 of the bearing plate 4 to fix the two sides of the bearing plate 4. Then, the two motors 5 are started again to move the bearing plate 4 into the support plate 1.
[0030] Then the first electric telescopic rod 9 is started. The telescopic end of the first electric telescopic rod 9 drives the two base plates 3 to move down synchronously in the corresponding slide groove 11, thereby driving the car steel plate 19 to be cut down to the cutting platform 2.
[0031] Then the second electric telescopic rod 17 and the cutter 18 are started. The cutter 18 cuts the car steel plate 19 to be cut on the cutting platform 2.
[0032] Finally, the two motors 5 are started to move the two support plates 4 synchronously out of the end face of the support plate 1, where workers remove them and proceed with the next batch of cutting work, repeating the cycle.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
