Description

Technical Field

[0001] This utility model relates to the field of elevator shaft roughing and finishing technology, specifically a high-efficiency precision grinding device that integrates roughing and finishing of elevator shafts. Background Technology

[0002] The elevator shaft is a key transmission component in an elevator system, primarily used to transmit power and bear rotational motion. As the core connecting component between the traction machine (drive unit) and the traction sheave, it transmits the rotational torque of the motor to the traction sheave, driving the steel wire rope to pull the elevator car.

[0003] Application number CN202121977936.1 discloses a steel rod driving grinding device for a steel rod grinding machine, relating to the field of steel rod grinding technology. This utility model includes a base plate and other structures. By setting up a grinding mechanism with upper and lower grinding wheels respectively inside, the upper and lower grinding wheels simultaneously grind the steel rod, improving grinding efficiency. Furthermore, by setting up a flipping mechanism, this utility model transfers the ground steel rod, allowing the grinding mechanism to grind another steel rod simultaneously, thus improving work efficiency.

[0004] In practical use, although the application achieves continuous flow of steel bars and parallel operation of grinding through the flipping mechanism, its core grinding mechanism can only process a single steel bar at a time. This single-station processing mode significantly limits the output efficiency per unit time, and its inherent capacity is difficult to meet the requirements when facing the demand for large-scale batch production. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A high-efficiency precision grinding device integrating rough and fine machining of elevator shafts includes a grinding mechanism and a clamping mechanism. The grinding mechanism includes a shell, a hollow grinding roller rotatably installed inside the shell, a side plate sleeved at one end of the shell, and a motor connected between the hollow grinding roller and the side plate. The shell has multiple assembly ports. The clamping mechanism includes a base plate at the bottom of the shell, two hydraulic cylinders connected between the shell and the base plate, multiple supports connected to multiple corners of the base plate, multiple stops installed inside the supports, a pressure rod interference-fitted to the inside of the stops, and a spring connected between the shell and the pressure rod. The inner end of the pressure rod slides into the assembly port.

[0008] By adopting the above technical solution, after placing elevator shafts in multiple assembly ports, the movable end of the hydraulic cylinder is controlled to retract, driving the stop block to push the pressure rod to continuously insert into the assembly port until the pressure rod is tightly fitted with the elevator shaft, thus completing the fixing of the elevator shaft. Subsequently, the motor is started to drive the hollow grinding roller to rotate, realizing the simultaneous grinding of multiple elevator shafts, thereby improving production efficiency.

[0009] In a preferred embodiment, the present invention can be further configured such that: the motor body is fixedly connected to the outer wall of the side plate, the motor output shaft rotates through the side plate, and is connected to the hollow grinding roller.

[0010] In a preferred embodiment, this invention can be further configured as follows: two hydraulic cylinders are connected in series, and the hydraulic cylinders are electrically connected to an external power source.

[0011] In a preferred embodiment, the present invention can be further configured such that: the pressure rod is composed of a trapezoidal block and a T-shaped rod, the T-shaped rod is integrally formed on the inner side of the trapezoidal block, and the T-shaped rod is inserted into the shell.

[0012] In a preferred embodiment, the present invention can be further configured such that the spring is movably sleeved on the outside of the T-shaped rod, and the spring is located between the shell and the trapezoidal block.

[0013] In a preferred embodiment, the present invention can be further configured as follows: multiple arc pads are fixed to the inner wall of the shell cylinder, and the multiple arc pads are arranged in groups of three, forming two groups. The two groups of arc pads are located at both ends of the shell cylinder, and the three arc pads in each group are evenly spaced and arranged in a ring around the outer side of the hollow grinding roller. The inner side of the arc pads is in contact with the outer wall of the hollow grinding roller.

[0014] In a preferred embodiment, the present invention can be further configured such that: a clamp is movably sleeved on the outer side of the shell, the clamp is located between two hydraulic cylinders, and the clamp is made of shape memory metal material.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, after placing elevator shafts in multiple assembly ports, the movable end of the hydraulic cylinder is controlled to retract, driving the stop block to push the pressure rod to continuously insert into the assembly port until the pressure rod is tightly fitted with the elevator shaft, thus completing the fixing of the elevator shaft. Subsequently, the motor is started to drive the hollow grinding roller to rotate, realizing the simultaneous grinding of multiple elevator shafts, thereby improving production efficiency.

[0017] 2. In this utility model, during the grinding process, at regular intervals, the movable end of the hydraulic cylinder extends and retracts slightly once, causing the pressure rod to briefly relax the elevator shaft.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-efficiency precision grinding device that integrates rough and fine machining of elevator shafts.

[0032] Example 1:

[0033] Combination Figure 1-6As shown, the present invention provides a high-efficiency precision grinding device for the integrated rough and fine machining of elevator shafts, including a grinding mechanism 100 and a clamping mechanism 200. The grinding mechanism 100 includes a shell 110, a hollow grinding roller 120 rotatably installed inside the shell 110, a side plate 130 sleeved on one end of the shell 110, and a motor 140 connected between the hollow grinding roller 120 and the side plate 130. The shell 110 has multiple assembly ports.

[0034] The clamping mechanism 200 includes a base plate 210 disposed at the bottom of the shell 110, two hydraulic cylinders 220 connected between the shell 110 and the base plate 210, multiple supports 230 respectively connected to multiple corners of the base plate 210, multiple stops 240 installed on the inner side of the supports 230, a pressure rod 250 interference-fitted to the inner side of the stops 240, and a spring 260 connected between the shell 110 and the pressure rod 250. The inner end of the pressure rod 250 slides to the inside of the assembly opening.

[0035] Furthermore, the motor 140 body is fixedly connected to the outer wall of the side plate 130, and the output shaft of the motor 140 rotates through the side plate 130 and is connected to the hollow grinding roller 120. The connection method of the motor 140 ensures both the secure installation of the motor 140 and its ability to smoothly drive the hollow grinding roller 120 to rotate.

[0036] Furthermore, two hydraulic cylinders 220 are connected in series and electrically connected to an external power source. With this connection method, the moving ends of the two hydraulic cylinders 220 rise and fall synchronously, and then the shell 110 can rise and fall horizontally, avoiding jamming when the shell 110 rises and falls.

[0037] Furthermore, the pressure rod 250 is composed of a trapezoidal block 251 and a T-shaped rod 252. The T-shaped rod 252 is integrally formed on the inner side of the trapezoidal block 251. The T-shaped rod 252 is inserted into the shell 110. The structural design of the pressure rod 250 allows the shell 110 to descend and the pressure rod 250 to be pressed into the assembly port by itself.

[0038] Furthermore, the spring 260 is movably sleeved on the outside of the T-shaped rod 252. The spring 260 is located between the shell 110 and the trapezoidal block 251. The layout design of the spring 260 can flexibly push the trapezoidal block 251 outward, ensuring that the pressure rod 250 can flexibly press the elevator shaft in the assembly port.

[0039] Example 2:

[0040] Combination Figure 1 and Figure 3As shown, based on Embodiment 1, a plurality of arc pads 300 are fixed to the inner wall of the shell 110. The arc pads 300 are arranged in groups of three, forming two groups. The two groups of arc pads 300 are located at both ends of the shell 110. The three arc pads 300 in each group are evenly spaced and arranged in a ring around the outer side of the hollow grinding roller 120. The inner side of the arc pads 300 is in contact with the outer wall of the hollow grinding roller 120. The arc pads 300 can fill the gap between the hollow grinding roller 120 and the shell 110, making the rotation of the hollow grinding roller 120 more stable.

[0041] Example 3:

[0042] Combination Figure 1 As shown, in the above embodiment, a clamp 400 is movably sleeved on the outer side of the shell 110. The clamp 400 is located between two hydraulic cylinders 220. The clamp 400 is made of shape memory metal material. The clamp 400 provides conditions for adjusting the elevator shaft angle and ensures that the entire outer wall surface of the elevator shaft can be polished.

[0043] The working principle and usage process of this utility model are as follows: In the initial state, the movable ends of both hydraulic cylinders 220 are in an extended state. During operation, the shell cylinder 110 is first lifted, which drives the spring 260 to press the trapezoidal block 251, causing the T-shaped rod 252 to slide towards both ends of the assembly opening, thereby preventing it from blocking the insertion of the elevator shaft. After the equipment is in place, the clamp 400 is rotated to expose the assembly openings one by one. The operator then places the elevator shaft into the assembly opening. Next, the movable end of the hydraulic cylinder 220 is retracted, which drives the stop block 240 to push the pressure rod 250 into the assembly opening until the pressure rod 250 is tightly fitted with the elevator shaft, thus fixing the elevator shaft. Subsequently, the motor 140 is started to drive the hollow grinding roller 120 to rotate, realizing the simultaneous grinding of multiple elevator shafts. During the grinding process, at regular intervals, the movable end of the hydraulic cylinder 220 is slightly extended or retracted, causing the pressure rod 250 to briefly loosen the elevator shaft. At this time, the operator rotates the clamp 400, using friction to drive the elevator shaft to rotate, changing its contact position with the grinding roller. This cycle is repeated until the entire outer wall of the elevator shaft is ground, effectively improving the grinding efficiency.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
