Description
Technical Field
[0001] The utility model relates to the technical field of scissor platforms, and more specifically, to a scissor-type aerial work platform with slag cleaning function. Background Art
[0002] A scissor lift platform (hereinafter referred to as a scissor platform) is a lift platform with a scissor structure as the extension mechanism, which transports personnel, tools, and materials to the working position through the extension of the scissor structure. Scissor platforms are widely used in fields such as construction, warehousing and logistics, shipbuilding, airports, indoor and outdoor decoration, and large exhibition halls.
[0003] The basic structure of a scissor platform includes a chassis assembly, an extension mechanism, and a working platform, etc. On the upper surface of the chassis assembly, a chute is provided; on the lower surface of the working platform, a chute is also provided. At the bottom and top of the extension mechanism, sliders that can slide in the chute are provided. The extension mechanism is connected to the chassis assembly through the slider at the bottom and is connected to the working platform through the slider at the top.
[0004] When the scissor platform is performing a lifting operation, the horizontal movement of the sliders of the extension mechanism in the chutes of the chassis assembly and the working platform is used to adjust the angle between the scissor arms of the extension mechanism, thereby changing the relative height between the working platform and the ground, and realizing the lifting and lowering of the scissor platform. During daily construction operations, sundries generated by construction will fall on the chute of the chassis assembly. If not cleaned in time, the accumulation, hardening, or caking of sundries will generate resistance to the sliding of the slider, and even damage the structure of the slider and the chute. For example, it will cause abnormal wear of the slider or make the chute pitted, thereby affecting the service life and safety performance of the equipment. Therefore, after the equipment completes construction, the operator needs to actively clean the chute and slider of the scissor platform to ensure that the slider can slide smoothly in the chute, but this increases the working intensity of the operator.
[0005] In summary, how to improve the sliding effect and service life of the scissor platform is an urgent problem to be solved by those skilled in the art at present. Content of the Utility Model
[0006] In view of this, the purpose of the utility model is to provide a scissor-type aerial work platform with slag cleaning function, which can effectively improve the sliding effect and service life of the scissor platform.
[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0008] A scissor-type aerial work platform with slag cleaning function, comprising:
[0009] A chassis assembly, on the upper surface of which a chute is provided;
[0010] A working platform, on its lower surface is provided with the chute;
[0011] An extension mechanism, which includes a scissors arm assembly and a driving member for pushing the scissors arm assembly to unfold and fold. Sliders are provided at both the bottom and the top of the scissors arm assembly, and the sliders are connected in cooperation with the chute. Wherein, a shovel-shaped obstacle clearing block is provided on the moving side of the slider.
[0012] In one embodiment, the slider includes a main body portion and the obstacle clearing block detachably connected to the main body portion.
[0013] In one embodiment, the obstacle clearing block is fixed to the main body portion by bolts.
[0014] In one embodiment, the obstacle clearing block is provided on one side or both sides of the main body portion.
[0015] In one embodiment, the obstacle clearing block includes a polyurethane material piece, a hard nylon material piece or a steel material piece.
[0016] In one embodiment, the obstacle clearing block includes an obstacle clearing bottom fitting the chute, an obstacle clearing slope and a vertical portion vertically provided on one side of the obstacle clearing bottom;
[0017] The bottom of the obstacle clearing slope is connected to the obstacle clearing bottom, the top of the obstacle clearing slope is connected to the vertical portion, the angle between the obstacle clearing slope and the obstacle clearing bottom is an acute angle, and the vertical portion is used for connecting with the slider.
[0018] In one embodiment, the acute angle is 15° - 35°.
[0019] In one embodiment, a scissors fixing end is provided on the upper surface of the chassis assembly, the rear fixing end of the scissors arm assembly is connected to the scissors fixing end, and the slider is provided at one end opposite to the rear fixing end.
[0020] In one embodiment, the driving member includes a hydraulic cylinder, the fixed end of the hydraulic cylinder is provided in the middle of the chassis assembly, and the driving end of the hydraulic cylinder is connected to the scissors arm assembly.
[0021] When using the scissor - type aerial work platform with slag - clearing function provided by the present utility model, the driving member can be controlled to operate to push the scissor arm assembly to unfold or fold, thereby realizing the lifting or lowering operation of the work platform. During the unfolding or folding process of the scissor arm assembly, the slider will move along the chute. When sundries fall on the chute, the obstacle - clearing block will clean the chute in real - time during the movement of the slider, avoiding the accumulation, hardening or caking of sundries. That is, the shovel - shaped obstacle - clearing block will clean the sundries in the chute in real - time as the slider moves during the lifting operation of the extension mechanism, keeping the sliding track of the slider (i.e., the chute part where the slider reciprocates) clean and smooth for sliding.
[0022] After the equipment completes the construction, the operator only needs to regularly check, clean and replace the obstacle - clearing block, without replacing the entire slider, reducing the frequency of the operator cleaning the chute and the slider, and reducing the labor intensity of the operator. At the same time, the obstacle - clearing block can prevent the slider from directly contacting sundries, playing a protective role for the slider and reducing the risk of damage to the structures of the slider and the chute.
[0023] In summary, the scissor - type aerial work platform with slag - clearing function provided by the present utility model can effectively improve the sliding effect and service life of the scissor platform. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] The core of the present invention is to provide a scissor-type aerial work platform with a slag cleaning function, which can effectively improve the sliding effect and service life of the scissor platform.
[0033] Please refer to Figures 1 to 4 , wherein, Figure 1 is a schematic structural diagram of the scissor-type aerial work platform with a slag cleaning function provided by the present invention; Figure 2 is Figure 1 front view of Figure 3 is a schematic structural diagram of the extension mechanism; Figure 4 is a schematic structural diagram of the debris clearing block.
[0034] This specific embodiment provides a scissor-type aerial work platform with a slag cleaning function, including:
[0035] The chassis assembly 1, on the upper surface of which there is a chute 4;
[0036] The working platform 2, on the lower surface of which there is a chute 4;
[0037] The extension mechanism 3, which includes a scissors arm assembly 31 and a driving member for pushing the scissors arm assembly 31 to unfold and fold. Sliders 32 are provided at both the bottom and the top of the scissors arm assembly 31, and the sliders 32 are connected in cooperation with the chute 4. Among them, a shoveled debris clearing block 33 is provided on the moving side of the slider 32.
[0038] It should be noted that the sliding block 32 and the sliding groove 4 are connected in a matching manner, which means that the extension mechanism 3 can be connected to the chassis assembly 1 through the sliding block 32 at the bottom, and the extension mechanism 3 can be connected to the working platform 2 through the sliding block 32 at the top. The obstacle clearing block 33 is set in a shovel-like structure, that is, the obstacle clearing block 33 can be set in a structure similar to a shovel or a sweeping bucket, so as to better utilize the obstacle clearing block 33 to clean sundries. In the actual application process, the shape, structure, size, material, position, etc. of the chassis assembly 1, the working platform 2, and the extension mechanism 3 can be determined according to the actual situation and actual needs.
[0039] When using the scissor-type aerial work platform with slag cleaning function provided by the present utility model, the driving member can be controlled to operate to push the scissor arm assembly 31 to unfold or fold, so as to realize the lifting or lowering operation of the working platform 2. During the unfolding or folding process of the scissor arm assembly 31, the sliding block 32 will move along the sliding groove 4. When sundries fall on the sliding groove 4, the obstacle clearing block 33 will clean the sliding groove 4 in real time during the movement of the sliding block 32, avoiding the accumulation, hardening or caking of sundries. That is, the shovel-shaped obstacle clearing block 33 will clean the sundries in the sliding groove 4 in real time as the sliding block 32 moves during the lifting operation of the extension mechanism 3, so that the sliding track of the sliding block 32 (that is, the part of the sliding groove 4 where the sliding block 32 reciprocates) remains clean and the sliding is smooth.
[0040] After the equipment completes the construction, the operator only needs to regularly inspect, clean and replace the obstacle clearing block 33, without replacing the entire sliding block 32, reducing the frequency of the operator cleaning the sliding groove 4 and the sliding block 32, and reducing the labor intensity of the operator. At the same time, the obstacle clearing block 33 can prevent the sliding block 32 from directly contacting sundries, play a protective role for the sliding block 32, and reduce the risk of damage to the structures of the sliding block 32 and the sliding groove 4.
[0041] In summary, the scissor-type aerial work platform with slag cleaning function provided by the present utility model can effectively improve the sliding effect and service life of the scissor platform.
[0042] In one embodiment, the sliding block 32 includes a main body portion 34 and an obstacle clearing block 33 detachably connected to the main body portion 34. That is, a detachable obstacle clearing block 33 is designed on the sliding block 32, and when the obstacle clearing block 33 is damaged by sundries, the detachable structure makes the replacement operation of the obstacle clearing block 33 more convenient.
[0043] In one embodiment, the obstacle clearing block 33 is fixed to the main body portion 34 by bolts 35. That is, the obstacle clearing block 33 can be connected to the main body portion 34 by bolts 35, so as to facilitate the installation or disassembly of the obstacle clearing block 33.
[0044] In one embodiment, the obstacle clearing block 33 is provided on one side or both sides of the main body portion 34.
[0045] It should be noted that the moving side of the obstacle clearing block 33 can be marked as the front end, and the other side as the rear end. The obstacle clearing block 33 can be arranged at the front end of the main body 34, or at the rear end of the main body 34, or at both the front and rear ends of the main body 34. When sundries fall on the chute 4, the obstacle clearing block 33 will clean the chute 4 in real time during the movement of the slider 32, avoiding the accumulation, hardening or caking of sundries.
[0046] In one embodiment, the obstacle clearing block 33 includes a polyurethane material part, a hard nylon material part or a steel material part to ensure the wear resistance and a certain hardness of the obstacle clearing block 33, ensuring that the obstacle clearing block 33 can smoothly clean sundries and will not be easily worn.
[0047] In one embodiment, the obstacle clearing block 33 includes an obstacle clearing bottom 36 arranged to fit the chute 4, an obstacle clearing slope 37, and a vertical part 38 vertically arranged on one side of the obstacle clearing bottom 36; the bottom of the obstacle clearing slope 37 is connected to the obstacle clearing bottom 36, the top of the obstacle clearing slope 37 is connected to the vertical part 38, and the angle between the obstacle clearing slope 37 and the obstacle clearing bottom 36 is an acute angle. The vertical part 38 is used to connect with the slider 32, and the structure is as shown in the figure. Therefore, when the slider 32 slides along the chute 4, the obstacle clearing bottom 36 is in close contact with the chute 4, and the obstacle clearing slope 37 can effectively clean sundries. Of course, the obstacle clearing slope 37 can also be set as a concave structure.
[0048] In one embodiment, the acute angle is 15° - 35° to ensure that the end of the obstacle clearing block 33 is sharper and can better clean the sundries on the chute 4. The angle of the acute angle can be determined according to the actual situation and actual needs during the actual operation process.
[0049] It should be noted that a sensor or a camera can be arranged on the chute 4 to detect the condition of the part of the chute 4 where the slider 32 reciprocates through the sensor or the camera. And both the sensor (or camera) and the driving part can be connected to the control device, and the control device can also be connected to the prompting device. If the sensor (or camera) detects the accumulation, hardening or caking of sundries in the part of the chute 4 where the slider 32 reciprocates, it indicates that the obstacle clearing effect of the obstacle clearing block 33 may fail. At this time, the prompting device can perform a prompting operation to facilitate the operator to timely discover the failure of the obstacle clearing block 33 and then perform replacement and repair operations on the obstacle clearing block 33. Of course, a sensor or a camera for detecting whether the obstacle clearing block 33 is worn can also be added to directly judge whether the obstacle clearing block 33 fails.
[0050] In one embodiment, a scissor fixed end 11 is arranged on the upper surface of the chassis assembly 1, the rear fixed end 39 of the scissor arm assembly 31 is connected to the scissor fixed end 11, and the slider 32 is arranged at the end opposite to the rear fixed end 39.
[0051] It should be noted that the rear fixed end 39 of the scissor arm assembly 31 is connected to the scissor fixed end 11 of the chassis assembly 1, and the slider 32 of the scissor arm assembly 31 is arranged in the chute 4 of the chassis assembly 1. When the scissor arm assembly 31 performs a lifting operation, the position of the scissor fixed end 11 does not change. By moving the slider 32 in the chute 4, the angle between the scissor arms of the scissor arm assembly 31 is adjusted, so that the distance between the slider 32 at the top of the extension mechanism 3 and the slider 32 at the bottom of the extension mechanism 3 changes, thereby changing the relative height between the working platform 2 and the ground, and realizing the lifting and lowering operations of the scissor arm assembly 31.
[0052] In one embodiment, the driving member includes a hydraulic cylinder. The fixed end of the hydraulic cylinder is arranged in the middle of the chassis assembly 1, and the driving end of the hydraulic cylinder is connected to the scissor arm assembly 31. Therefore, by controlling the operation of the hydraulic cylinder, the scissor arm assembly 31 can be extended or folded, thereby changing the relative height between the working platform 2 and the ground, and realizing the lifting and lowering of the scissor arm assembly 31.
[0053] In addition, it should be noted that the orientation or positional relationship indicated by "up and down", "top and bottom", etc. in the present invention is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of simplified description and understanding, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.
