Description

Technical Field

[0001] This application relates to the field of safety protection technology for working at heights, specifically a high-altitude work lift that can self-detect its height for protection. Background Technology

[0002] With the advancement of industrialization, an increasing number of high-altitude operations require the use of scissor lifts. Aerial work platforms are specialized equipment for high-altitude operations and are widely used in construction, maintenance, installation, and other fields. They provide a safe and stable working platform, enabling operators to perform various tasks in the air. The main function of an aerial work platform is to raise the work platform to the required height for workers to operate. Scissor lifts, in particular, are widely used in various high-altitude work scenarios due to their stable structure, high load-bearing capacity, and smooth lifting.

[0003] Currently, as the lifting height of scissor lifts increases, so do the safety hazards. Existing scissor lift platforms typically rely on mechanical limits and manual monitoring to ensure the lifting height remains within a safe range. However, these methods often have limitations. Mechanical limits often fail to reflect the real-time height of the lift platform in a timely and accurate manner, and are easily affected by equipment aging or improper operation. Secondly, manual monitoring depends on the operator's experience and judgment, which can lead to accidents if the lift platform gets too close to the work surface, potentially hitting workers. This makes it difficult to cope with complex working environments and changing safety requirements. Utility Model Content

[0004] The purpose of this application is to provide a high-altitude work platform vehicle that can self-detect height for protection, in order to solve the problems mentioned in the background art, where mechanical limit switches often fail to reflect the real-time height of the lifting platform in a timely and accurate manner, and are easily affected by equipment aging or improper operation. Secondly, manual monitoring relies on the experience and judgment of the operators, which can lead to the lifting platform getting too close to the work surface and hitting the workers, making it difficult to cope with complex working environments and changing safety requirements.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-altitude work platform vehicle capable of self-detecting height for protection, comprising a main body of the platform vehicle, a laser rangefinder sensor, and a support platform, wherein the support platform is disposed on the top of the main body of the platform vehicle;

[0006] The top of the support platform is symmetrically equipped with protective components on the left and right sides, and a fixing component is fixedly installed on the outside of the support platform. The laser range sensor is movably installed on the outside of the fixing component.

[0007] The protective assembly includes two guide frames and an electric push rod fixedly installed on the top of the support platform. The two guide frames are arranged symmetrically front to back. The electric push rod is located in the center inside the two guide frames. Limiting sliders are movably engaged inside the two guide frames. A support rod is fixedly connected to the top of the limiting slider. A crossbar is fixedly installed on the top of the support rod. A trigger plate is movably installed on the top of the crossbar. A touch sensor located below the trigger plate is fixedly installed on the top of the crossbar. The electric push rod is connected to the crossbar and is used to push the crossbar up and down.

[0008] Preferably, the electric push rod is set at the same height as the guide frame.

[0009] Preferably, the top of the crossbar has a first mounting groove symmetrically arranged front and back and a second mounting groove centrally located. An elastic sleeve is fixedly installed inside the first mounting groove, and the elastic sleeve is fixedly connected to the bottom of the trigger pressure plate.

[0010] Preferably, the touch sensor is disposed inside the second mounting slot.

[0011] Preferably, the fixing component includes a connecting block and a locking block. The connecting block is fixedly installed on the outside of the bearing platform, and the locking block is fixedly installed on the inside of the laser ranging sensor. The connecting block has a top-opening slot inside, and the locking block is movably engaged in the slot. Rectangular openings are provided on both the left and right sides of the connecting block. An elastic plate is fixedly installed on the outside of the rectangular opening, and a buckle is fixedly connected to the inside of the elastic plate. A buckle groove corresponding to the buckle is provided on the outside of the locking block, and the buckle is movably engaged in the buckle groove.

[0012] Preferably, both the card slot and the card block are arranged in a "T" shape.

[0013] Preferably, the laser rangefinder is arranged vertically.

[0014] Preferably, it also includes a console, which is mounted on the carrier platform.

[0015] Preferably, it further includes a laser rangefinder and a fixing component; the fixing component is fixedly installed on the outside of the support platform, and the laser rangefinder is movably installed on the outside of the fixing component.

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] 1. By installing a liftable protective component on the outside of the carrying platform in conjunction with a laser rangefinder, the protective component extends to provide necessary protection for the operator when the platform is raised for use. When the safe distance is exceeded, the control console receives a signal from the protective component, issues an alarm, and stops the raising. During the ascent of the carrying platform, the laser rangefinder continuously monitors the distance between the carrying platform and the top. The protective component and the laser rangefinder work together to provide protection based on changes in height, effectively reducing safety risks.

[0018] 2. By pulling the elastic plate outward to deform it, the buckle is released from the slot. Then, the laser rangefinder sensor is moved upward along the slot, causing the inner block to slide out of the slot. This facilitates quick disassembly and installation of the laser rangefinder sensor, thereby improving the convenience of maintaining the laser rangefinder sensor. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1, Figure 2 , Figure 3 , Figure 4 and Figure 5 This application provides a technical solution: a high-altitude work platform vehicle capable of self-detecting height for protection, comprising a main body 1, a laser rangefinder 6, and a support platform 2 mounted on top of the main body 1. A control console 3 and two protective components 4 are fixedly installed on the top of the support platform 2, symmetrically arranged on the left and right sides of the top of the support platform 2. A fixing component 5 is fixedly installed on the outer side of the support platform 2, and the laser rangefinder 6 is movably mounted on the outside of the fixing component 5. Each protective component 4 includes two guide frames 41 and an electric push rod 42 fixedly installed on the top of the support platform 2. The two guide frames 41 are symmetrically arranged front and rear, and the electric push rod 42 is centrally located inside the two guide frames 41. A limit slider 43 is movably engaged inside each of the two guide frames 41. A support rod 44 is fixedly connected to the top of the limit slider 43, and a crossbar 45 is fixedly installed on the top of the support rod 44. A trigger plate 46 is movably installed on the top of the platform 2, and a touch sensor 47 located below the trigger plate 46 is fixedly installed on the top of the crossbar 45. The electric push rod 42 is connected to the crossbar 45 and is used to push the crossbar 45 up and down. When the platform 2 is raised, the electric push rod 42 pushes the crossbar 45 upward, causing the support rod 44 and the limit slider 43 to slide upward within the guide frame 41. The lifting height of the crossbar 45 can provide necessary protection for the operator. When the trigger plate 46 contacts the top surface and presses downward, it will trigger the touch sensor 47. The control console 3 receives the signal, issues an alarm, and stops the lifting. During the ascent of the platform 2, the laser range sensor 6 continuously monitors the distance between the platform 2 and the top. Once the height exceeds the safe range, the control console 3 will issue an alarm and stop the platform from rising. The protective component 4 works in conjunction with the laser range sensor 6 to provide protection based on height changes, effectively reducing safety risks.

[0027] The electric push rod 42 is set at the same height as the guide frame 41.

[0028] The electric push rod 42 is at the same height as the guide frame 41 to ensure that its thrust can be evenly transmitted to the crossbar 45, avoiding uneven force due to height difference, thereby extending the service life of the equipment.

[0029] The top of the crossbar 45 has a first mounting groove 451 symmetrically arranged at the front and back and a second mounting groove 452 arranged in the center. An elastic sleeve 48 is fixedly installed inside the first mounting groove 451. The elastic sleeve 48 is fixedly connected to the bottom of the trigger plate 46. The design of the elastic sleeve 48 can effectively reduce the impact force when the trigger plate 46 is pressed down, ensuring that the triggering process is smooth and sensitive.

[0030] The touch sensor 47 is located inside the second mounting slot 452.

[0031] The trigger portion of the touch sensor 47 is located at the top and protrudes from the second mounting groove 452. It can be accurately triggered when the trigger plate 46 is pressed down, while avoiding the trigger plate 46's downward pressure from acting entirely on the touch sensor 47. This ensures the sensitivity of the trigger while avoiding excessive pressure on the touch sensor 47.

[0032] Please see Figure 2 and Figure 5 The fixing component 5 includes a connecting block 51 and a locking block 52. The connecting block 51 is fixedly installed on the outside of the bearing platform 2, and the locking block 52 is fixedly installed on the inside of the laser rangefinder 6. The connecting block 51 has a top-opening slot 53 inside, and the locking block 52 is movably engaged in the slot 53. Rectangular openings 54 are opened on both the left and right sides of the connecting block 51. An elastic plate 55 is fixedly installed on the outside of the rectangular opening 54, and a buckle 56 is fixedly connected to the inside of the elastic plate 55. A buckle groove 57 corresponding to the buckle 56 is opened on the outside of the locking block 52, and the buckle 56 is movably engaged in the buckle groove 57. By pulling the elastic plate 55 outward to deform it, the buckle 56 is released from the buckle groove 57. Then, the laser rangefinder 6 is moved upward along the slot 53, so that the locking block 52 inside it slides out of the slot 53, which facilitates quick disassembly and installation of the laser rangefinder 6, thereby improving the convenience of maintaining the laser rangefinder 6.

[0033] Both the slot 53 and the block 52 are T-shaped, which can effectively prevent the block 52 from accidentally falling out of the slot 53, ensuring the stability of the connection. At the same time, it simplifies the installation and disassembly process, enabling maintenance personnel to carry out inspection and replacement work in a short time, further improving the overall efficiency of the equipment.

[0034] The laser rangefinder 6 is set vertically to ensure the accuracy of its measurements.

[0035] Working principle: The operator stands on the support platform 2 and operates the control console 3 to control the lifting vehicle body 1 to rise. As the support platform 2 rises, the control console 3 automatically controls the electric push rod 42 to work. The electric push rod 42 extends, causing the crossbar 45 to move upward. The upward movement of the crossbar 45 causes the support rod 44 and the limit slider 43 to slide upward within the guide frame 41. The height of the crossbar 45 exceeds the operator's height, providing protection. The trigger plate 46 contacts the top of the working surface. As the support platform 2 rises, the trigger plate 46 is pressed, causing the elastic sleeve 48 to retract. In turn, the trigger plate 46 presses down, triggering the touch sensor. Device 47 receives a signal from touch sensor 47 via control console 3 to trigger an alarm and stop raising. When the support platform 2 is raised, laser rangefinder 6 starts working. Laser rangefinder 6 faces the top of the work surface and monitors the height between the support platform 2 and the top of the work surface in real time by transmitting and receiving laser rangefinders. When laser rangefinder 6 detects that the height exceeds the safe distance, it transmits a signal to control console 3 to trigger the alarm built into control console 3 and stop raising via control console 3. When laser rangefinder 6 operates in conjunction with protective component 4, it provides protection based on the height and reduces safety hazards.

[0036] When the laser rangefinder 6 needs maintenance after prolonged use, disconnect the wiring of the laser rangefinder 6, pull the elastic plate 55 outward to deform the elastic plate 55, causing the buckle 56 to disengage from the buckle groove 57. Then, pull the laser rangefinder 6 upward along the groove 53, causing the laser rangefinder 6 to drive the locking block 52 out of the groove 53. This facilitates quick disassembly and assembly of the laser rangefinder 6, improving the convenience of maintenance. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0037] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
