Description

Technical Field

[0001] This utility model belongs to the field of work platform technology, specifically a hydraulic lifting work platform with safety outriggers. Background Technology

[0002] A hydraulic lifting platform is a lifting device driven by hydraulic power. Its core components include hydraulic cylinders, pistons, valve groups, and oil pumps. The oil pump, driven by an electric motor or engine, pumps hydraulic oil into the hydraulic cylinders, pushing the pistons up or down, thereby raising or lowering the platform.

[0003] To meet specific engineering needs, current hydraulic lifting work platforms are designed with outriggers at the four corners to provide more support and stability. However, in actual use, it has been found that the ground may be uneven or have a certain slope in different working environments. Currently, the hydraulic outriggers are all set vertically downwards, which can lead to insufficient support when in contact with uneven or sloped ground, indicating room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic lifting work platform with safety outriggers in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: A hydraulic lifting work platform with safety outriggers includes a work platform, a base and a positioning block. The base is provided with a steering mechanism at each of its four corners. The rotating end of the steering mechanism is provided with an outrigger mechanism for supporting the base. The steering mechanism includes an outer ring body and an inner disc body rotatably disposed in the outer ring body. Multiple sets of teeth are distributed at equal intervals along the outer peripheral surface of the inner disc body. The outer ring body is also provided with a locking block that is adapted to and engages with the teeth. The end of the positioning block facing away from the teeth is also provided with a pushing member. The pushing member is used to drive the locking block to disengage from and / or engage with the teeth.

[0006] In a preferred embodiment, the locking block has teeth that are adapted to the tooth pattern at one end facing the tooth pattern, and the outer ring body has a cavity that allows the locking block to reciprocate.

[0007] In a preferred embodiment, the pushing element is a push rod motor.

[0008] In a preferred embodiment, the outer ring body has a plurality of mounting holes spaced apart circumferentially, and the outer ring body is fastened to the base by a plurality of bolts. The outer ring body is formed with an annular groove that satisfies the tooth pattern embedding by avoiding circumferential recesses, and the annular groove is connected to the cavity.

[0009] In a preferred embodiment, the outrigger mechanism includes a hydraulic cylinder and a chassis. The back of the housing of the hydraulic cylinder is mounted on the outer wall of the inner disc. The hydraulic cylinder can rotate with the inner disc. The telescopic end of the hydraulic cylinder is connected to a spherical connector. The bottom of the spherical connector is rotatably connected to a pre-reserved groove on the top of the chassis.

[0010] In a preferred embodiment, the chassis is omnidirectionally rotatable relative to the spherical connector, and a pressure sensor is also embedded in the bottom surface of the chassis.

[0011] In a preferred embodiment, the work platform is located above the base, and a hydraulic scissor lift is also provided between the base and the work platform.

[0012] In a preferred embodiment, the top perimeter of the work platform is provided with an openable fence, and the fence is equipped with a controller electrically connected to the hydraulic scissor lift, pressure sensor, hydraulic cylinder, and pusher. In another preferred embodiment, the base is also provided with wheels at the four corners of its bottom.

[0028] Reference Figure 1-3 A hydraulic lifting work platform with safety outriggers includes a work platform 100, a base 300, and a positioning block. The base 300 is equipped with a steering mechanism 700 at each of its four corners. The rotating end of the steering mechanism 700 is equipped with an outrigger mechanism 600 for supporting the base 300. The designed steering mechanism 700 can meet the rotation operation of the outrigger mechanism 600 and the subsequent retrieval operation of the outrigger mechanism 600, ensuring the overall support strength and safety. It has a wider range of applications and can increase the extension height of the outrigger mechanism 600 compared to the traditional vertical outrigger mechanism 600 (without occupying too much space when retracted laterally).

[0029] In this embodiment, refer to Figure 3As shown, the steering mechanism 700 includes an outer ring body 710 and an inner disc body 730 rotatably disposed within the outer ring body 710. Multiple sets of teeth 740 are evenly spaced along the outer circumferential surface of the inner disc body 730. A locking block 750 adapted to engage with the teeth 740 is also provided within the outer ring body 710. A pushing member 720 is provided at the end of the locking block 750 facing away from the teeth 740. The pushing member 720 is used to drive the locking block 750 to disengage from and / or engage with the teeth 740. Teeth adapted to the teeth 740 are provided at the end of the locking block 750 facing the teeth 740. A cavity 760 is provided within the outer ring body 710 to allow for the reciprocating movement of the locking block 750. The pushing member 720 is a push rod motor. Multiple sets of teeth 740 are evenly spaced along the outer circumferential surface of the inner disc body 730. The outer ring 710 is secured to the base 300 with multiple mounting holes and bolts. The outer ring 710 has an annular groove inside to allow for the insertion of the toothed 740, avoiding circumferential recesses. This groove is connected to the cavity 760. When the steering mechanism 700 needs to be rotated, the pusher 720 drives the locking block 750 away from the toothed 740. At this time, the outrigger mechanism 600 can be rotated left or right, allowing for the retraction of the outrigger mechanism 600 or adjustment of its angle. After adjustment, the pusher 720 drives the locking block 750 towards and engages with the toothed 740. Through the cooperation of the toothed 740 and the locking block 750, the angle of the outrigger mechanism 600 can be locked.

[0030] In this embodiment, refer to Figure 2 As shown, the outrigger mechanism 600 includes a hydraulic cylinder 610 and a chassis 630. The back of the housing of the hydraulic cylinder 610 is mounted on the outer wall of the inner chassis 730. The hydraulic cylinder 610 can drive the chassis 630 to move downward, so that the bottom surface of the chassis 630 is lower than the position of the traveling wheels 400. The hydraulic cylinder 610 can support the working platform, which can ensure the stability during operation and avoid the problem of the working platform moving or shaking on its own.

[0031] In this embodiment, refer to Figure 2 As shown, the hydraulic cylinder 610 can rotate with the inner plate 730. The telescopic end of the hydraulic cylinder 610 is connected to a ball joint 620. The bottom of the ball joint 620 is rotatably connected to a pre-reserved groove on the top of the chassis 630. The chassis 630 can rotate omnidirectionally relative to the ball joint 620. A pressure sensor 640 is also embedded in the bottom surface of the chassis 630. An omnidirectional micro-motion mechanism is designed at the connection between the chassis 630 and the hydraulic cylinder 610. When the chassis 630 contacts the ground, the angle of the chassis 630 can be adjusted according to the unevenness of the ground by using the cooperation between the ball joint 620 and the chassis 630 to ensure the stability of the support. At the same time, the pressure sensor 640 on the chassis 630 monitors the downward pressure. Based on the pressure values ​​monitored by the pressure sensors at the four corners of the chassis 630, it can be determined whether the force is uniform at each position, thereby ensuring the safety of subsequent use.

[0032] In this embodiment, referring to Figure 1 as shown, the working platform 100 is located above the base 300. A hydraulic scissor lift 500 is also provided between the base 300 and the working platform 100. By extending and folding the hydraulic scissor lift 500, the height adjustment of the working platform 100 can be achieved to meet the use in working environments with different heights.

[0033] Further, a fence that can be opened is provided on the top periphery of the working platform 100. A controller 200 electrically connected to the hydraulic scissor lift 500, a pressure sensor 640, a hydraulic cylinder 610, and a pusher 720 is provided on the fence. Of course, in other embodiments, a remote controller can also be provided externally to control the overall linkage work through the remote controller (not shown in the figure). A display screen can be reserved on the remote controller or the controller 200.

[0034] In this embodiment, referring to Figure 1 as shown, universal wheels 400 are further provided at the four corners of the bottom of the base 300. When it is necessary to move the position of the working platform 100, the leg mechanism 600 is retracted, and the working platform 100 can be assisted to move by the universal wheels 400. The universal wheels 400 are preferably used.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
