Description

Technical Field

[0001] The utility model relates to the technical field of aerial work equipment, and more specifically to a self-propelled leg-belt aerial work vehicle. Background Art

[0002] Aerial work vehicles are special vehicles used to transport workers and equipment to the site for aerial work. They have the characteristics of multiple varieties and small batches, and are widely used in large-scale aerial work such as stations, docks, shopping malls, stadiums, residential properties, factories and mines.

[0003] When the operators are working on the work platform, if there is a certain distance between the work platform and the work position, the operators need to communicate with the driver in the cab at high altitude. The driver operates the lifting lever to adjust the work platform, but the driver is not in the same position as the operators. Language communication cannot quickly move the work platform to the best working position, which makes the movement of the work platform very troublesome and reduces the efficiency of high-altitude operations.

[0024] See also Figure 1-Figure 3 A self-propelled leg-belt aerial work vehicle comprises: a transverse control box 1, a transverse transmission threaded rod 8 is rotatably connected between the inner walls on both sides of the transverse control box 1, a transverse transmission block 9 is threadedly connected to the transverse transmission threaded rod 8, the transverse transmission block 9 slides through the upper inner wall of the transverse control box 1, a longitudinal control box 3 is fixedly connected to the top of the transverse transmission block 9, a longitudinal transmission threaded rod 11 is rotatably connected between the inner walls on both sides of the longitudinal control box 3, a longitudinal transmission block 13 is threadedly connected to the longitudinal transmission threaded rod 11, the longitudinal transmission block 13 slides through the upper inner wall of the longitudinal control box 3, and a work support platform 5 is fixedly connected to the top of the longitudinal transmission block 13.

[0025] In a specific embodiment of the utility model, when the operator is on the high-altitude work support platform 5, by controlling the rotation of the horizontal transmission threaded rod 8, the horizontal transmission block 9 can be driven to move, so that the longitudinal control box 3 moves in the horizontal direction, thereby driving the work support platform 5 to move in the horizontal direction. By controlling the rotation of the longitudinal transmission threaded rod 11, the longitudinal transmission block 13 can be driven to move in the longitudinal direction, thereby driving the work support platform 5 to move in the longitudinal direction. When the operator of the work vehicle moves the work platform to the vicinity of the specified position, the operator does not need to communicate with the operator, and can control the work support platform 5 to make a shorter displacement in the horizontal and longitudinal directions, thereby eliminating the step of communicating with the operator. The process of moving the work support platform 5 to the working position is simpler, thereby improving the efficiency of high-altitude operations.

[0026] Specifically, two transverse support rods 10 are fixedly connected between the inner walls on both sides of the transverse control box 1 , and the transverse transmission block 9 is slidably sleeved on the two transverse support rods 10 .

[0027] In this embodiment, the two lateral support rods 10 can keep the lateral transmission block 9 in stable movement, thereby increasing the stability of the overall structure.

[0028] Specifically, a transverse driving motor 2 is fixedly mounted on an outer surface of one side of the transverse control box 1 , and an output end of the transverse driving motor 2 is fixedly connected to a transverse transmission threaded rod 8 .

[0029] In this embodiment, the transverse transmission threaded rod 8 can be driven to rotate by controlling the transverse drive motor 2 to start.

[0030] Specifically, two longitudinal support rods 12 are fixedly connected between the inner walls on both sides of the longitudinal control box 3 , and the longitudinal transmission block 13 is slidably sleeved on the two longitudinal support rods 12 .

[0031] In this embodiment, the two longitudinal support rods 12 can ensure that the longitudinal transmission block 13 maintains stable movement, thereby increasing the stability of the overall structure.

[0032] Specifically, a longitudinal drive motor 4 is fixedly mounted on an outer surface of one side of the longitudinal control box 3 , and an output end of the longitudinal drive motor 4 is fixedly connected to the longitudinal transmission threaded rod 11 .

[0033] In this embodiment, the longitudinal transmission threaded rod 11 can be driven to rotate by controlling the longitudinal drive motor 4 to start.

[0034] Specifically, a support plate 6 is fixedly connected to an outer surface of one side of the longitudinal control box 3 , and a plurality of pulleys 7 are fixedly installed on the bottom of the work support platform 5 .

[0035] In this embodiment, the support plate 6 is in contact with the pulley 7. The support plate 6 can support the work support platform 5 to increase the stability of the work support platform 5. The pulley 7 makes the friction of the work support platform 5 smaller when it moves.

[0036] Working principle: When the operator is on the high-altitude work support platform 5, by controlling the start of the lateral drive motor 2, the lateral transmission threaded rod 8 can be driven to rotate, and the lateral transmission block 9 can be driven to move, so that the longitudinal control box 3 moves in the transverse direction, thereby driving the work support platform 5 to move in the transverse direction. By controlling the start of the longitudinal drive motor 4, the longitudinal transmission threaded rod 11 can be driven to rotate, and the longitudinal transmission block 13 can be driven to move in the longitudinal direction, thereby driving the work support platform 5 to move in the longitudinal direction. When the operator of the work vehicle moves the work platform to the vicinity of the specified position, the operator does not need to communicate with the operator, and can control the work support platform 5 to make a shorter displacement in the transverse and longitudinal directions, thereby eliminating the step of communicating with the operator. The process of moving the work support platform 5 to the working position is simpler, which improves the efficiency of high-altitude work. The control method of the utility model is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model no longer explains the control method and wiring layout in detail.

[0037] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
