Description

Technical Field

[0001] This utility model belongs to the field of lifting tower technology, specifically, it relates to a mobile hydraulic lifting tower. Background Technology

[0002] As a key piece of equipment in scenarios such as high-altitude operations, communication signal transmission, and emergency rescue, the performance of the lifting tower directly determines the effectiveness of the operation and operational safety. In high-altitude operation scenarios, it is necessary to move quickly to the designated work point and fix it stably. If the mobility is insufficient, it will delay the operation.

[0003] Traditional lifting towers typically have fixed-installation casters (such as swivel casters), which cannot be easily switched between ground contact and detachment. When moving, the casters are in constant contact with the ground, which can cause the equipment to shift due to bumps. When stationary, the casters are difficult to retract completely, and can easily slip due to ground vibration or external force, seriously affecting the stability of the support. Furthermore, some lifting towers lack angle adjustment mechanisms for their casters, resulting in insufficient contact with the ground and high rolling resistance.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a mobile hydraulic lifting tower.

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

[0007] A mobile hydraulic lifting tower includes a base and a lifting tower body. A first movable block is fixedly connected to the bottom of the base. An adjusting rod is hinged to the first movable block. A caster wheel is fixedly provided at the bottom of the adjusting rod. A second movable block is fixedly connected to the bottom of the base. A U-shaped plate is hinged to the second movable block. A hydraulic rod is fixedly provided on the U-shaped plate. A third movable block is fixedly connected to the end of the piston rod of the hydraulic rod. The third movable block is hinged to the adjusting rod. A support assembly is provided on the base.

[0008] Preferably, a first reinforcing plate is fixedly connected to the base, and a second reinforcing plate is fixedly connected to the base, with the first reinforcing plate located above the second reinforcing plate to increase the load-bearing capacity of the base.

[0009] Preferably, the support assembly includes a sleeve with a threaded rod threaded through it, and a support plate is fixedly connected to the top of the threaded rod to provide stable support for the base.

[0010] Preferably, a turntable is fixedly connected to the top of the threaded rod, and the turntable is coaxial with the threaded rod to facilitate the rotation and movement of the threaded rod.

[0011] Preferably, a support plate is slidably connected to the base, the support plate is fixedly connected to the sleeve, and the support plate is slidably connected to the second reinforcing plate to adjust the support position.

[0012] Preferably, the support plate has a threaded hole, and the second reinforcing plate is threaded with a bolt, the bolt thread penetrating the support plate to limit the position of the support plate after adjustment.

[0013] Preferably, the support components are provided in four sets, which are evenly distributed on the base to provide stable support for the base.

[0014] In summary, the technical effects and advantages of this utility model are as follows: This mobile hydraulic lifting tower operates through hydraulic rods, and the coordinated use of the first movable block, the second movable block, the U-shaped plate, and the third movable block adjusts the position of the casters. When moving, the casters descend to the ground, maximizing the contact area and reducing rolling resistance. At the same time, the casters fold upwards and detach from the ground to avoid accidental sliding that could interfere with the stability of the support.

[0015] The combined use of the first and second reinforcing plates increases the load-bearing capacity of the base. The supporting components provide stable support for the base. Furthermore, the contact point with the ground can be adjusted to adapt the support plate to the unevenness of the ground or the required support spacing, thereby increasing the stability of the lifting tower body.

[0021] This utility model provides a mobile hydraulic lifting tower. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0022] Reference Figure 1-3 A mobile hydraulic lifting tower includes a base 1 and a lifting tower body 2. Four first movable blocks 3 are fixedly connected to the bottom of the base 1, evenly distributed at the four corners of the bottom of the base 1. Adjusting rods 4 are hinged to the first movable blocks 3, and casters 5 are fixedly mounted on the bottom of the adjusting rods 4, located at the center of the bottom of the adjusting rods 4. A second movable block 6 is fixedly connected to the bottom of the base 1, and a U-shaped plate 7 is hinged to the second movable block 6. A hydraulic rod 8 is fixedly mounted on the U-shaped plate 7, with the hydraulic rod 8 inclined. The fixed end of the hydraulic rod 8 is securely attached to the U-shaped plate 7, and a third movable block 9 is fixedly connected to the end of the piston rod of the hydraulic rod 8. The components include the first movable block 3, adjusting rod 4, casters 5, second movable block 6, and U-shaped plate. 7. The number of hydraulic rods 8 and the third movable block 9 are equal and correspond one-to-one. The third movable block 9 is hinged to the adjusting rod 4. A support assembly 10 is provided on the base 1. There are four sets of support assemblies 10, which are evenly distributed on the base 1. The support assembly 10 is used to stabilize the base 1. When the hydraulic rod 8 operates, it applies an external force to the adjusting rod 4 through the cooperation of the second movable block 6, the U-shaped plate 7 and the third movable block 9. The adjusting rod 4 moves and adjusts under the action of the first movable block 3, thereby adjusting the position of the caster wheel 5 so that the caster wheel 5 is in contact with or separated from the ground, which is convenient for storing the caster wheel 5 and avoids accidental sliding that may interfere with the stability of the support. When moving, the caster wheel 5 lands on the ground, maximizing the contact area and reducing rolling resistance.

[0023] Reference Figure 1-2 A first reinforcing plate 11 is fixedly connected to the base 1. Five first reinforcing plates 11 are provided and are evenly distributed on the base 1. A second reinforcing plate 12 is fixedly connected to the base 1. The first reinforcing plates 11 are located above the second reinforcing plates 12. Two second reinforcing plates 12 are provided and are evenly distributed on the base 1. The first reinforcing plates 11 and the second reinforcing plates 12 increase the load-bearing capacity of the base 1.

[0024] Reference Figure 1 , Figure 2 and Figure 4The support assembly 10 includes a sleeve 101, a threaded rod 102 threaded through the sleeve 101, the outer side wall of the threaded rod 102 being adapted to the inner side wall of the sleeve 101, and a support plate 103 fixedly connected to the top of the threaded rod 102, the cross-sectional area of ​​the support plate 103 gradually increasing from top to bottom.

[0025] Reference Figure 2 and Figure 4 A turntable 104 is fixedly connected to the top of the threaded rod 102. The turntable 104 is coaxial with the threaded rod 102. After the turntable 104 rotates, the threaded rod 102 rotates and moves accordingly.

[0026] Reference Figure 2 and Figure 4 A support plate 105 is slidably connected to the base 1. The support plate 105 is located between the base 1 and the sleeve 101. The support plate 105 is fixedly connected to the sleeve 101. The support plate 105 is slidably connected to the second reinforcing plate 12. The support plate 105 can adjust the contact point between the support plate 103 and the ground.

[0027] Reference Figure 2 and Figure 4 The support plate 105 has a threaded hole 106, and the second reinforcing plate 12 is threaded with a bolt 107. The bolt 107 is adapted to the threaded hole 106, and the bolt 107 thread passes through the support plate 105. After the support plate 105 is moved to a suitable position, the threaded hole 106 thread passes through the second reinforcing plate 12 and the support plate 105, thereby limiting the position of the support plate 105.

[0028] Working principle: The turntable 104 drives the threaded rod 102 to rotate upward along the sleeve 101, causing the support plate 103 to lift off the ground. At this time, the caster wheel 5 contacts the ground, providing support for movement. The hydraulic rod 8 extends and retracts, pushing the adjusting rod 4 to rotate around the hinge point of the first movable block 3 through the second movable block 6, the U-shaped plate 7, and the third movable block 9, adjusting the position of the caster wheel 5. This allows the caster wheel 5 to be adjusted to be in contact with or separated from the ground, facilitating its storage. Simultaneously, it facilitates stable support of the base 1 by the support assembly 10, allowing for adjustment as needed. The position of the tower body 2 can be flexibly adjusted. The turntable 104 is rotated in the opposite direction, and the threaded rod 102 is screwed downward along the sleeve 101. The support plate 103 touches the ground and gradually supports the base 1 until the caster 5 leaves the ground, completing the stable support in the vertical direction. The sliding support plate 105 is adjusted to a horizontal position along the base 1 and the second reinforcing plate 12 so that the support plate 103 adapts to the uneven ground or the support spacing requirements. The bolt 107 is tightened so that it passes through the threaded hole 106 of the support plate 105 and is screwed to the second reinforcing plate 12, locking the position of the support plate 105.
