Description

Technical Field

[0001] This application relates to the field of vehicle-mounted lifting equipment technology, and in particular to a vehicle-mounted scissor lift platform. Background Technology

[0002] Vehicle-mounted scissor lifts are widely used in construction, power maintenance, and advertising installation, primarily to safely elevate workers to high positions for operations. With the rapid development of urban construction, the demand for aerial work platforms is increasing daily. Vehicle-mounted scissor lifts, due to their high mobility and ease of operation, have gradually become one of the mainstream aerial work tools on the market. This equipment not only improves work efficiency but also significantly reduces the risks of working at heights, ensuring the safety of workers.

[0003] In existing vehicle-mounted scissor lift platforms, the following methods are commonly used to achieve flexible movement of the work platform: first, adjusting the position of the work platform by moving the vehicle itself; second, changing the height and tilt of the work platform by manually adjusting the angle of the scissor arms; and third, achieving horizontal rotation of the work platform through a rotating mechanism mounted on the work platform. These methods can meet operational needs to a certain extent, but they still have limitations in certain specific scenarios.

[0004] However, the above methods have revealed some problems in practical applications. In particular, when the work platform is raised and operators need to make precise adjustments in multiple directions at high altitudes, relying solely on vehicle movement and scissor arm adjustments is insufficient to meet the operational needs in complex environments. Furthermore, traditional scissor lift platforms have limited lateral movement capabilities of the work platform, failing to achieve flexible adjustments in other directions, which restricts their applicability and flexibility in a wider range of application scenarios. Utility Model Content

[0005] To overcome the aforementioned technical problems, this application provides a vehicle-mounted scissor lift platform.

[0006] This application provides a vehicle-mounted scissor lift platform, which adopts the following technical solution:

[0007] A vehicle-mounted scissor lift platform includes a vehicle and a lifting platform. The vehicle includes a truck bed, and the lifting platform is placed inside the truck bed. The lifting platform includes a scissor arm, a hydraulic drive assembly, and a work platform. The work platform includes a movable base and a work platform base. A translation mechanism is provided between the movable base and the work platform base. The work platform base has sliding grooves at both ends, and the movable base has a slider at its bottom. The translation mechanism includes a translation hydraulic cylinder and a fixed plate. The translation hydraulic cylinder is fixedly mounted on one end of the fixed plate. The fixed plate has an elongated groove forming a travel groove. A circular hole seat is fixedly provided on the output shaft. The translation mechanism also includes a rotating bracket and a follower bracket. The rotating bracket is opposite to the translation hydraulic cylinder and is slidably disposed in the travel groove via a sliding shaft. A linkage shaft is fixedly provided at the end of the follower bracket and is slidably disposed in the travel groove. The circular hole seat is rotatably connected to the linkage shaft. The middle part of the follower bracket and the rotating bracket is rotatably connected via a constraint bolt. Rollers are provided at the ends of the follower bracket and the rotating bracket away from the fixed plate. The translation mechanism also includes an arc-shaped sliding groove formed at the bottom of the movable base.

[0008] By adopting the above technical solution, the translation hydraulic cylinder can be activated via commands issued from the control console. Once activated, the translation hydraulic cylinder begins to drive the follower bracket to slide along the travel groove. During this process, the angle between the follower bracket and the rotating bracket gradually decreases, while their length also increases. The rollers located within the arc-shaped slide groove begin to move along the track of the slide groove, moving inward from the outer end. The moving base propels forward with the cooperation of the slide groove and the slider. This coordinated action achieves smooth movement of the worktable. The translation hydraulic cylinder is positioned on the opposite side of the worktable's direction of movement, balancing the effect of gravity and preventing the worktable from tipping over due to excessive gravity when it extends.

[0009] In one specific implementation, the hydraulic drive assembly includes a primary hydraulic cylinder, a secondary hydraulic cylinder, and a tertiary hydraulic cylinder, which are fixedly arranged on the same side of the scissor arm from top to bottom.

[0010] By adopting the above technical solution, the first-stage hydraulic cylinder, second-stage hydraulic cylinder and third-stage hydraulic cylinder set on the same side can save on the layout of hydraulic pipelines, making the pipelines laid on the scissor arm more reasonable.

[0011] In one specific implementation, the support mechanism includes an extension arm hinged to the side end of the truck bed, the extension arm being arranged in a rectangular shape on the side end of the truck bed, and two support cylinders being fixedly mounted on each extension arm.

[0012] By adopting the above technical solution, the setting of two support cylinders can increase the support force and improve the overall stability of the workbench during operation.

[0013] In one specific implementation scheme, a warning light is fixedly installed on the top of each of the support cylinders.

[0014] By adopting the above technical solution, the warning light serves to provide warnings and indicate boundaries.

[0015] In one specific implementation scheme, a foot is fixedly provided at the end of the output shaft of the support cylinder, and an insulating rubber plate is fixedly connected to the foot.

[0016] By adopting the above technical solution, the insulating rubber sheet plays an insulating role, preventing workers and equipment from being shocked by electric shock.

[0017] In one specific implementation, the workbench includes a fence that is fixedly mounted on top of the mobile base.

[0018] In one specific implementation, a control console is fixedly installed on the fence.

[0019] In one specific implementation scheme, a front guardrail and a rear guardrail are fixedly installed at the front and rear ends of the truck bed, respectively.

[0020] By adopting the above technical solution, the fence, front baffle, and rear baffle are set up to provide protection, and the control console on the fence makes it easier for workers to adjust their position on the work platform.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The translation mechanism includes a translation hydraulic cylinder, a fixed plate, and a series of rotating and following supports. Commands issued from the control console drive the translation hydraulic cylinder to move the worktable smoothly, making the worktable's movement more stable and efficient.

[0023] 2. The support mechanism includes an extendable arm hinged to the side of the truck bed and support cylinders fixed to it. These cylinders not only provide stable support but also increase the overall stability of the work platform during operation. Meanwhile, the warning lights serve as both warning and indicator lights, improving equipment safety. Regarding equipment safety, the use of insulating rubber mats prevents electric shock to workers and equipment, enhancing operational safety. The installation of guardrails, control consoles, and front and rear windshields further provides better protection for operators. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] This application discloses a vehicle-mounted scissor lift platform, referring to... Figure 3 and Figure 4The system includes a vehicle 1, a support mechanism, and a lifting platform. The vehicle 1 includes a truck bed 11, and the lifting platform is placed inside the truck bed 11, enabling long-distance transportation using the vehicle 1. The lifting platform includes a scissor arm 2, a hydraulic drive assembly, and a work platform 61. The work platform 61 includes a movable base 63 and a work platform base 64, with a translation mechanism between the movable base 63 and the work platform base 64. The work platform base 64 has sliding grooves 67 at both ends, and the movable base 63 has a slider 66 at its bottom. The work platform base 64 and the movable base 63 slide relative to each other through the sliding grooves 67 and the slider 66. The translation mechanism includes a translation hydraulic cylinder 51 and a fixed plate 52, which are positioned opposite to the direction of movement of the work platform 61. A translational hydraulic cylinder 51 is fixedly mounted on one end of a fixed plate 52. The fixed plate 52 has an elongated groove forming a moving groove 521. A circular hole seat 53 is fixedly mounted on the output shaft of the translational hydraulic cylinder 51. The translation mechanism also includes a rotating bracket 56 and a follower bracket 55. The rotating bracket 56 is opposite to the translational hydraulic cylinder 51 and is slidably mounted in the moving groove 521 via a sliding shaft. A linkage shaft 54 ​​is fixedly mounted at the end of the follower bracket 55. The linkage shaft 54 ​​is slidably mounted in the moving groove 521. The circular hole seat 53 is rotatably connected to the linkage shaft 54, so that both ends of the linkage shaft 54 ​​are limited by the circular hole seat 53 and the follower bracket 55 respectively, so that the linkage shaft 54 ​​can slide stably in the moving groove 521. The follower bracket 55 and the rotating bracket 56 are rotatably connected at their middle parts by a constraint bolt 58. The constraint bolt 58 connects the follower bracket 55 and the rotating bracket 56, allowing them to rotate relative to each other along the constraint bolt 58. The top and bottom of the constraint bolt 58 are rotatably inserted into the movable base 63 and the worktable base 64, respectively. Both the follower bracket 55 and the rotating bracket 56 are equipped with rollers 57 at their ends away from the fixed plate 52. The translation mechanism also includes an arc-shaped groove 65 formed at the bottom of the movable base 63, within which the two rollers 57 are rotatably disposed.

[0031] Reference Figure 1 and Figure 2The hydraulic drive assembly includes a primary hydraulic cylinder 31, a secondary hydraulic cylinder 32, and a tertiary hydraulic cylinder 33. These cylinders are fixedly mounted sequentially from top to bottom on the same side of the scissor arm 2. During operation, the hydraulic drive assembly drives the primary hydraulic cylinder 31, secondary hydraulic cylinder 32, and tertiary hydraulic cylinder 33 in sequence, allowing the work platform 61 to rise gradually. The support mechanism includes an extension arm 41 hinged to the side of the truck bed 11. The extension arms 41 are rectangularly arranged on the side of the truck bed 11, and each extension arm 41 is fixedly equipped with two support cylinders 42. The hinged arrangement of the extension arms 41 allows them to fold and retract towards the truck bed 11 after use, shortening the width of the truck bed 11. Warning lights 43 are fixedly mounted on the top of each support cylinder 42 to indicate the working status of the lifting platform. Foot 44 is fixedly mounted at the end of the output shaft of the support cylinder 42, and an insulating rubber plate 45 is fixedly connected to the foot 44. The insulating rubber sheet 45 is used to insulate the vehicle 1 from the ground. The work platform 61 includes a fence 62, which is fixedly mounted on the top of the movable base 63. A control console is fixedly mounted on the fence 62. The control console allows workers standing on the work platform 61 to control the translation mechanism, thereby controlling the movement of the work platform 61. At the same time, the control console can also control the hydraulic drive assembly to drive the work platform 61 to rise and fall.

[0032] The front and rear ends of the truck bed 11 are respectively fixedly equipped with a front guardrail 12 and a rear guardrail 13. The front guardrail 12 extends towards the top of the front of the truck and can protect the cab from being hit by falling objects.

[0033] The implementation principle of this application embodiment is as follows: A worker stands on the operating platform and uses a control console to control the height of the work platform 61. When it is lifted to the position to be constructed, if the position of the work platform 61 needs to be adjusted, the position of the work platform 61 can be adjusted in two directions by moving the vehicle 1. With the setting of the translation mechanism, if the worker needs to move closer to the construction point, the translation hydraulic cylinder 51 is activated by controlling the control console. The translation hydraulic cylinder 51 drives the follower bracket 55 to slide along the travel groove 521, reducing the angle between the follower bracket 55 and the rotating bracket 56 and extending the follower bracket 55 and the rotating bracket 56. The roller 57 located in the arc-shaped slide groove 65 moves inward from the outer end of the arc-shaped slide groove 65 along the trajectory of the arc-shaped slide groove 65, and pushes the moving base 63 forward along the slide groove 67 and the slider 66, thereby realizing the movement of the work platform 61. When the translation mechanism drives the work platform 61 to move, since the translation hydraulic cylinder 51 is set in the opposite position to the direction of movement of the work platform 61, this setting makes the gravity evenly distributed and avoids the work platform 61 from tipping over due to excessive gravity when it extends.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
