Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, and in particular to a building wall repair lifting trolley. Background Technology

[0002] Building wall repairs require work at heights, and a lifting trolley is a mobile aerial work platform specifically designed for this purpose. It typically features adjustable height, a stable working platform, safe load capacity, flexible vertical lifting, and good turning and climbing capabilities, making it convenient for cleaning, repairing, painting, tiling, and other operations on complex building facades.

[0003] However, most traditional building wall repair lifting trolleys only achieve position adjustment by moving horizontally and vertically, lacking detailed and stable control of the base at different ground and wall angles. This can easily lead to deviations in scenarios with uneven ground or non-vertical walls, thus affecting the applicable scope of the building wall repair lifting trolley.

[0004] Therefore, those skilled in the art have provided a building wall repair lifting trolley to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a building wall repair lifting trolley. This trolley is equipped with a translation mechanism, which allows adjustment of the support plate by engaging a first hexagonal locking block with a wrench, thereby extending the support legs from the first storage slot and lifting the base. This changes the direction of the base's movement in both the longitudinal and transverse directions, enabling the lifting trolley to move smoothly across the building wall. This facilitates smooth advancement or retraction at different wall locations, improving the coverage area and ease of use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A building wall repair lifting trolley includes a base. A translation mechanism is provided in the middle of the lower surface of the base. The translation mechanism includes a positioning ring, a first storage groove, a bidirectional screw, and a second storage groove. A support leg is hinged to the inner wall of the first storage groove. A roller is rotatably connected to the lower end of the support leg. A connecting shaft is rotatably connected to the middle of the inner wall of the support leg. A support plate is fixedly connected to the middle of the outer wall of the connecting shaft. First hexagonal locking blocks are fixedly connected to the outer walls on both sides of the bidirectional screw. A limiting groove is formed on the inner top surface of the second storage groove. A limiting slider is slidably connected to the inner wall of the limiting groove.

[0008] The upper surface of the base is provided with a horizontal mechanism, which includes a positioning seat, a first guide rail, an arc-shaped guide frame, and a hinge seat. A first one-way screw is rotatably connected to the middle of the outer wall of the front end of the positioning seat. A second hexagonal locking block is fixedly connected to the outer wall of the front end of the first one-way screw. A first guide slider is slidably connected to both the front end and the rear end of the outer wall of the first guide rail. A rail groove is opened on both sides of the lower surface of the first guide slider. A support rod is hinged to both sides of the upper surface of the first guide slider. A base plate is hinged to the upper end of the hinge seat. A hinge ball is fixedly connected to both sides of the lower surface of the base plate. An arc-shaped slider is fixedly connected to the middle of the outer walls on both sides of the base plate.

[0009] The upper end of the horizontal mechanism is provided with a lifting mechanism, which includes a first storage box, a first lifting leg, a second lifting leg, and a hinge block. The upper end of the first storage box is hinged to a top plate, and a guardrail is fixedly connected to the upper surface of the top plate. The middle of the lower surface of the top plate is fixedly connected to a second storage box. The front and rear ends of the top surface inside the second storage box are both fixedly connected to a third guide rail, and a third guide slider is slidably connected to the outer wall of the third guide rail.

[0010] Through the above technical solution, the building wall repair lifting trolley is equipped with a horizontal mechanism. It can use a wrench to engage the second hexagonal locking block to control the first guide sliders at both ends to move forward or backward synchronously on the first guide rail. In turn, it works with the hinge ball and hinge seat to adjust the angle of inclination between the base plate and the wall, so that the base plate can be kept in a relatively stable horizontal position. This allows the lifting trolley to be used on ground with different inclination angles, further improving the applicability of the lifting trolley.

[0011] Furthermore, the outer walls of the front and rear ends of the base are provided with multiple connecting grooves, and the front and rear ends of the lower surface of the base are rotatably connected with multiple self-locking casters.

[0012] The above technical solution enables users to move the base by connecting the rope and the connecting groove, and then using the self-locking casters.

[0013] Furthermore, the positioning rings are respectively fixedly connected to the upper ends of the middle part of the outer walls on both sides of the base, and the upper ends of the outer walls of the positioning rings are threaded with first locking bolts. The bidirectional screw is rotatably connected to the center of the upper ends of the outer walls on both sides of the base, and the bidirectional screw is threadedly engaged with the limiting slider.

[0014] The above technical solution enables the first locking bolt to lock and restrict the bidirectional screw rotating inside the positioning ring.

[0015] Furthermore, the first storage slots are respectively opened at the front and rear ends on both sides of the lower surface of the base, the second storage slots are respectively opened at the middle of both sides of the lower surface of the base, and the upper end of the support plate is hinged to the limiting slider.

[0016] The above technical solution enables the components of the translation mechanism to be stored in the first and second storage slots.

[0017] Furthermore, the positioning seat is fixedly connected to the front end and rear end of the middle part of the upper surface of the base, the first guide slide rail is fixedly connected to both sides of the middle part of the upper surface of the base, and the first one-way screw is threadedly engaged with the first guide slider.

[0018] The above technical solution enables the first one-way screw to control the first guide slider to slide and adjust on the first guide rail.

[0019] Furthermore, the arc-shaped guide frame is fixedly connected to the middle of both sides of the upper surface of the base, the hinge seat is fixedly connected to both sides of the upper surface of the base, the arc-shaped slider slides on the inner wall of the arc-shaped guide frame, the front end and the rear end of one side of the outer wall of the arc-shaped slider are threaded with a second locking bolt, and the upper end of the support rod is hinged to the base plate.

[0020] The above technical solution enables the base plate to control the arc-shaped slider to slide on the inner wall of the arc-shaped guide frame, and then fixes and restricts the position of the arc-shaped slider by the second locking bolt, so as to adjust the horizontal orientation of the base.

[0021] Furthermore, the first storage box is fixedly connected to the middle of the upper surface of the base plate, and the first lifting leg and the second lifting leg are respectively hinged between the first storage box and the second storage box. The first lifting leg is hinged to the second lifting leg through a hinge block.

[0022] The above technical solution enables the coordination between the first lifting leg and the second lifting leg to control the rise or fall of the top plate.

[0023] Furthermore, a servo motor is fixedly connected to one side of the bottom surface of the first storage box, and a second one-way screw is fixedly connected to the output end of the servo motor. A second guide rail is fixedly connected to both the front end and the rear end of the bottom surface of the first storage box. A second guide slider is slidably connected to the outer wall of the second guide rail, and a threaded block is fixedly connected to the middle of the upper surface of the second guide slider.

[0024] The above technical solution enables the servo motor to control the second guide slider to slide on the second guide rail via the second unidirectional screw, thereby adjusting the position between the first lifting leg and the second lifting leg.

This lifts the support plate 407, causing the support legs 404 to extend from the first storage groove 403, allowing the rollers 405 to control the base 1 to slide horizontally along the wall, thus moving the lifting mechanism 6 to the desired position. Simultaneously, the wrench is engaged with the second hexagonal locking block 503, rotating the first unidirectional screw 502 to control the two first guide sliders 505 in the first guide... The system slides synchronously onto the slide rail 504, thereby adjusting the angle of inclination of the base plate 5010 relative to the wall in conjunction with the hinge ball 5011 and the hinge seat 509, so that the base plate 5010 can be in a horizontal position, thus allowing the lifting mechanism 6 to be parallel to the wall. Finally, the power is turned on to start the servo motor 602, which, in conjunction with the threaded engagement between the second one-way screw 603 and the threaded block 606, drives the second guide slider 605 to slide and translate on the second guide slide rail 604, thereby unfolding the first lifting leg 607 and the second lifting leg 608, so that the top plate 6010 is raised to lift the operator to a suitable height on the wall.
