Description

Technical Field

[0001] The utility model belongs to the technical field of elevator counterweight detection, and specifically discloses an elevator counterweight height limit detection and leveling integrated device. Background Art

[0002] The operation of traction elevators is based on a balance principle, that is, the elevator car and the counterweight are connected by traction wire ropes and move relative to each other under the drive of the motor. The main function of the counterweight is to balance the weight of the car and ensure that the traction force required by the elevator during the lifting process is minimized. This not only makes the elevator run more smoothly, but also significantly reduces the energy consumption of the motor, achieving the effect of energy saving and emission reduction. The purpose of the elevator counterweight height limit detection is to ensure that the size and installation position of the counterweight are appropriate and meet the design specifications and safety standards of the elevator shaft. If the counterweight is too high, it may cause unnecessary collision risks in the elevator shaft, affecting the stability of the elevator structure and passenger safety. The reasonable counterweight height is directly related to the energy saving effect and operating efficiency of the elevator. Too high or too low may lead to an imbalance in the traction demand, increase energy consumption and affect ride comfort.

The above device cannot adjust the height of the height limit detection device and is only suitable for workpiece detection of specified specifications. Therefore, it is urgent for technical personnel in this field to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to address the deficiencies of the above-mentioned prior art and to provide an integrated device for height limit detection and smoothing of an elevator counterweight. The integrated device for height limit detection and smoothing of an elevator counterweight transmits the elevator counterweight block to a height limit detection device and a smoothing device through a transmission component, and detects the height of the elevator counterweight block through the height limit detection device. If it does not meet the specified height, the part exceeding the standard height will be smoothed off through a limiting plate, and the upper and lower parts of the elevator counterweight block will be smoothed after being transmitted to the smoothing device.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An integrated device for height limit detection and smoothing of an elevator counterweight comprises a bracket, a conveying assembly, a height limit detection device and a smoothing device; the conveying assembly is used to transmit the counterweight to the height limit detection device and the smoothing device, the conveying assembly comprises a driving motor, a conveying roller and a transmission chain, the driving motor is connected to the transmission chain, the transmission chain is connected to the conveying roller, and the conveying roller is arranged in an array along the length direction of the bracket; the height limit detection device and the smoothing device are arranged directly above the conveying assembly; the height limit detection device comprises a photoelectric sensor, a reduction motor, a height limit detection rod and a push-pull device, the photoelectric sensor is mounted on the bracket, the reduction motor is mounted at the bottom of the bracket, the photoelectric sensor is electrically connected to the reduction motor, the push-pull device is mounted on the right side of the bracket, the reduction motor is electrically connected to the push-pull device, and the height limit detection rod is mounted on the bracket; the smoothing device comprises a smoothing sheet and a scraping plate, the smoothing sheet is fixedly mounted on the bracket and located above the conveying roller, and the scraping plate is mounted on the conveying roller.

[0007] Furthermore, the height limit detection device also includes a height limit detection rod fine-tuning structure, which is installed directly above the two ends of the height limit detection rod. The height limit detection rod fine-tuning structure includes a positioning rod, an adjusting handle and a limiting gear. The positioning rod is hinged on the bracket, and the adjusting handle is connected to the height limit detection rod through the limiting gear. When the positioning rod is in a horizontal position, it meshes with the limiting gear. The limiting gear and the adjusting handle are welded together, and the adjusting handle is connected to the height limit detection rod by bolts. A measuring ruler and a pointer are also provided at both ends of the height limit detection rod.

[0008] The introduction of the fine-tuning structure enables the operator to finely adjust the position of the height limit detection rod, and the limit gear is driven by the rotation of the adjustment handle to achieve a slight up and down movement of the height limit detection rod. This design greatly improves the accuracy of the detection rod position setting and ensures the accuracy of the height limit detection. Even when facing counterweights of different specifications or slight differences, appropriate adjustments can be made. The use of the adjustment handle makes the height limit adjustment more intuitive and simple. No complex tools are required. The operator only needs to turn the adjustment handle to quickly complete the height setting, which greatly shortens the adjustment time and improves work efficiency. The meshing design of the limit gear and the positioning rod, as well as the bolt connection between the adjustment handle and the height limit detection rod, ensure the stability of the entire fine-tuning structure. Even in the case of continuous use or external interference, the position of the height limit detection rod can be kept stable and unchanged, which improves the reliability of the equipment and the consistency of the test results. The measuring ruler and pointer at both ends of the height limit detection rod provide intuitive visual feedback for the operator, which is convenient for quickly checking and confirming the correctness of the height limit setting before and after adjustment, ensuring that each test can meet the expected accuracy requirements, and also facilitates daily calibration and maintenance work.

[0009] Furthermore, the height limit detection device also includes a height limit plate and a height limit plate height adjustment device, the height limit plate height adjustment device is installed on the bracket, the height limit plate is connected to the height limit plate height adjustment device, the height limit plate height adjustment device is a cylinder, and the height limit plate height adjustment device drives the height limit plate to move in the vertical direction.

[0010] The air cylinder is used as the height adjustment device of the height limit plate, which can quickly and accurately adjust the height of the height limit plate within a wide range. The pneumatic system has a fast response speed and controllable force, which enables the equipment to adapt to counterweights of different specifications and height requirements, improving the versatility and flexibility of the equipment. The automatic adjustment method driven by the air cylinder reduces the need for manual intervention. The automated adjustment process not only improves operating efficiency, but also reduces operating errors, ensuring that each adjustment can be accurately in place, which is suitable for continuous operation in large-scale production environments.

[0011] Furthermore, the height-limiting plate height-adjusting device is connected to the push-pull device; the push-pull device is an extended cylinder, and the push-pull device drives the height-limiting plate and the height-limiting plate height-adjusting device to move in the horizontal direction.

[0012] By connecting the height adjustment device of the height limit plate with the push-pull device, the height limit plate can not only adjust the height in the vertical direction, but also move in the horizontal direction. This two-dimensional adjustment capability greatly enhances the flexibility and adaptability of the equipment. Whether it is the change of the height of the counterweight block or the fine adjustment of the position, it can be easily handled to ensure the comprehensiveness and accuracy of the height limit detection and adjustment. The extended cylinder as a push-pull device can provide stable thrust and precise control, so that the height limit plate moves smoothly and accurately in the horizontal direction. This is especially important for occasions where height limit detection or processing is required at a specific location, ensuring that each movement can reach the predetermined position quickly and accurately.

[0013] Furthermore, the trowel device also includes a trowel blade height adjustment device, which is installed on the bracket and connected to the trowel blade. The trowel blade moves in the vertical direction driven by the trowel blade height adjustment device.

[0014] By adjusting the height of the trowel, it is possible to ensure that the trowel device can adapt to the counterweight surface of different thicknesses and heights, achieving a wider range of applicability. This is especially important on the production line. When it is necessary to process multiple types of counterweights, the trowel height can be quickly adjusted to reduce changeover time and improve production efficiency. Accurate trowel height adjustment can ensure that the trowel is close to the counterweight surface. Regardless of the amount of filling material, a uniform and consistent trowel effect can be achieved, avoiding material accumulation or unevenness caused by fixed trowel height, and improving the processing accuracy and surface quality of the counterweight.

[0015] Furthermore, a trowel plate shield is also provided on the trowel plate, and the trowel plate and the trowel plate shield are connected together by bolts.

[0016] The trowel blade guard can effectively shield the trowel blade in high-speed operation, prevent material splashing or debris ejection during operation, protect on-site operators from accidental injury, and also protect other parts of the equipment from accidental damage, improving the safety of the entire working environment. The guard can reduce the wear of the trowel blade edge caused by collision or friction, extend the service life of the trowel blade, and reduce maintenance and replacement costs. Especially when handling hard or impurity-containing filling materials, the protective effect of the guard is more significant.

[0017] Furthermore, the scraper plate is in close contact with the conveying roller.

[0018] The design of the scraper plate close to the conveyor roller ensures that the filling material on the surface can be evenly and continuously compressed and leveled when the counterweight passes through. This close contact can maximize the use of the pressure of the scraper plate, remove excess material, make the surface of the counterweight smoother, and improve the quality and appearance of the final product. Since the scraper plate fits tightly with the conveyor roller, it can effectively reduce or avoid the accumulation or residue of filling materials during the transmission process, keep the equipment clean, and reduce the need for subsequent cleaning and maintenance. At the same time, it avoids the risk of foreign matter jamming during elevator operation caused by residual materials. The close contact reduces the repetitive work of material handling, and efficient leveling can be completed in one pass, which speeds up the production rhythm, improves the overall production efficiency, and is conducive to meeting the needs of mass production and fast delivery.

[0019] The utility model has the following beneficial effects:

[0020] 1. By integrating the counterweight transmission, height limit detection and leveling operations into an integrated device, the workflow that previously required multiple independent steps and equipment to complete has been greatly simplified, significantly improving production efficiency. The automated transmission components ensure the accurate position of the counterweight during the detection and processing process, reducing errors caused by human operation and improving the accuracy of detection and processing;

[0021] 2. The height limit detection device uses a combination of photoelectric sensors and push-pull devices to monitor the height of the counterweight in real time. Once the preset limit is exceeded, the push-pull device driven by the reduction motor can react immediately and perform preliminary processing on the elevator counterweight through the height limit plate;

[0022] 3. The height of the height limit detection rod, the height limit plate and the leveling sheet are all adjustable, so that the device can perform height limit detection and leveling on more specifications of elevator counterweights, which improves the scope of application of the device.

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0030] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that an elevator counterweight height limit detection and leveling integrated device includes a bracket 1 constituting the main body of the device, and a transmission component 2 consisting of a driving motor 21, a transmission roller 22 and a transmission chain 23. The power of the driving motor 21 is transmitted to the transmission roller 22 through the transmission chain 23, so that the transmission rollers 22 arranged in an orderly manner in the length direction of the bracket 1 can smoothly move the elevator counterweight. The height limit detection device 2 integrates a photoelectric sensor 31, a reduction motor 32, a height limit detection rod 33 and a push-pull device 34. The photoelectric sensor 31 is responsible for monitoring the height of the counterweight, and adjusting the position of the height limit detection rod 33 through the electrically connected reduction motor 32 and the push-pull device 34. The height limit detection rod 33 is also equipped with a height limit detection rod fine-tuning structure 333, which allows the operator to accurately set the height by adjusting the handle 3332 and the limit gear 3333. At the same time, the measuring ruler 332 and the pointer 331 provide intuitive readings to ensure that the detection accuracy reaches the highest standard. The height limit plate 35 and the corresponding height limit plate height adjustment device 351 (using a pneumatic cylinder) provide dynamic height limit control capabilities, and the maximum height allowed to pass can be adjusted as needed. The linkage between the height limit plate height adjustment device 351 and the push-pull device 34 realizes flexible adjustment in both horizontal and vertical dimensions, enhancing the adaptability of the equipment. The leveling device 4 is located at the end of the counterweight transmission path and consists of a leveling sheet 41 and a scraping plate 43. The leveling sheet 41 can be moved in the vertical direction through the leveling sheet height adjustment device 42 to adapt to the leveling requirements of different counterweights, and is equipped with a leveling sheet shield 411 to ensure operation safety. The scraper plate 43 is directly mounted on the conveying roller 22 and is in close contact with the counterweight surface, ensuring efficient and uniform leveling during the conveying process.

[0032] In one embodiment, the installation position of the device is determined, the bracket 1 is ensured to be level, the bracket 1 is fixed to the ground with bolts, the bracket 1 is adjusted to ensure that it is completely stable, the drive motor 21 is fixed to the appropriate position of the bracket to ensure that it is aligned with the transmission chain 23, the conveyor rollers 22 are installed, and their positions on the bracket 1 are adjusted to ensure that the distance between the conveyor rollers 22 is appropriate and can stably carry the counterweight, the transmission chain 23 is connected, and its tension is adjusted to ensure that there is no slippage in power transmission, the photoelectric sensor 31 is fixed to the bracket to ensure that it is aligned with the moving path of the counterweight, and the reduction motor 32 and the push-pull device are installed. 34, connected to the photoelectric sensor 31 and the height limit detection rod 33, ensure that the electrical connection is correct, assemble the height limit detection rod fine-tuning structure 333, the adjustment handle 3332 and the limit gear 3333 need to be debugged to a smoothly adjustable state, install the height limit plate 35 and the height limit plate height adjustment device 351, install the smoothing plate 41 at the end of the bracket through the smoothing plate height adjustment device 42, ensure smooth adjustment, install the smoothing plate shield 411, fix it firmly, prevent safety hazards during operation, install the scraper plate 43 on the conveyor roller 22, and adjust its angle and pressure close to the counterweight surface;

[0033] When in use, the position of the height limit detection rod 33 can be adjusted according to needs. The height of the height limit detection rod 33 can be adjusted through the height limit detection rod fine adjustment structure 333. First, rotate the positioning rod 3331. Since the positioning rod 3331 is hinged on the bracket, the positioning rod 3331 can be rotated in the vertical direction. After rotating the positioning rod 33331, the limit gear 3333 is loosened. The position of the height limit detection rod 33 is adjusted by adjusting the handle 3332. According to the position of the pointer 331 on the measuring ruler 332, ensure that the height that matches the elevator counterweight to be detected is reached;

[0034] After the elevator counterweight is sensed by the photoelectric sensor 31, the height limit plate height adjustment device 351 is started through the reduction motor 32 to move the height limit plate 35 downward, and the height limit plate 35 is moved close to the elevator counterweight through the push-pull device 34. If the casting surface of the elevator counterweight is too high, the over-high part of the casting can be scraped off through the height limit baffle 35, and then the elevator counterweight, under the action of the transmission assembly 2, the casting completed counterweight block is uniformly sent into the leveling device 4.

[0035] Reference Figure 5 It can be seen that the smoothing device 4 includes a smoothing sheet 41 located above the conveying roller 22, the smoothing sheet 41 is installed in a smoothing sheet shield 411, the smoothing sheet 41 is also connected to a smoothing sheet height adjustment device 42, and a scraper plate 43 is installed on the bracket 1 and in contact with the conveying roller 22.

[0036] In one embodiment, the trowel sheet shield 411 is fixed to the predetermined position of the bracket 1 above the conveying assembly, and appropriate bolts are used to ensure that it is stable and correctly positioned. Note that the trowel sheet shield 411 should be able to completely surround the trowel sheet 41, leaving necessary openings for adjustment and maintenance, and the trowel sheet 41 is installed in the trowel sheet shield 411, ensuring that it matches the installation interface inside the trowel sheet shield 411, and connected through the trowel sheet height adjustment device 42. The trowel sheet adjustment device 42 should be pre-adjusted to an appropriate height to facilitate the initial installation of the trowel sheet 41. The trowel sheet 41 and the trowel sheet height adjustment device 42 are fixed by bolts to ensure that the connection is firm and the trowel sheet 41 can move up and down smoothly under the guidance of the trowel sheet height adjustment device 42. According to the installation position of the trowel sheet 41, the trowel sheet height adjustment device 42 is adjusted to an appropriate height to ensure that it cooperates with the trowel sheet guard 411 and the bracket 1 correctly. The trowel sheet height adjustment device 42 is connected to the bracket 1, and the scraper plate 43 is fixed on the bracket 1 to ensure that it is completely in contact with the surface of the conveyor roller 22.

[0037] In one embodiment, when the elevator counterweight moves smoothly to the position of the smoothing device 4 through the conveying assembly 2, it first passes through the scraping plate 43. The scraping plate 43 is made of stainless steel with a thickness of 0.5 mm. The scraping plate 43 is in contact with the conveying roller to smooth the bottom of the elevator counterweight and remove large protrusions or residues. The smoothing plate 41 is pre-adjusted to the expected height of the counterweight or slightly higher than the counterweight surface through the smoothing plate height adjustment device 42 to ensure that it can fully contact and apply appropriate pressure when the counterweight passes through, and perform delicate surface smoothing. As the elevator counterweight continues to move, the smoothing plate 41 with adjusted height is in close contact with the surface of the counterweight, and through its own design shape and material properties, the surface of the elevator counterweight is finely smoothed to eliminate minor unevenness and ensure that the final surface flatness meets the standards for elevator installation or maintenance. The smoothing plate shield 411 plays a role of protection and isolation in the whole process to prevent external factors from interfering with the smoothing process, and also protects operators and equipment from accidental injuries.

[0038] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments.
