Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for electromechanical maintenance, and in particular to an auxiliary lifting frame for electromechanical maintenance of highways. Background Technology

[0002] Highway high-altitude electromechanical systems refer to monitoring, communication, power supply, and information exchange equipment systems installed at high altitudes such as bridges and gantry cranes. These systems are used for traffic monitoring, data transmission, and intelligent management, and are key facilities for ensuring the efficient and safe operation of highways. Currently, scissor lifts are a common auxiliary lifting platform used for highway electromechanical maintenance.

[0003] Currently, maintenance personnel typically need to carry toolboxes to maintain high-altitude electromechanical equipment. However, scissor lifts do not have auxiliary placement structures, so maintenance personnel need to place the toolboxes on the standing surface of the scissor lift. Whenever maintenance personnel need to put down or retrieve tools, they have to bend over, which increases the burden on them and makes both use and maintenance inconvenient. Utility Model Content

[0004] Therefore, it is necessary to provide a new type of auxiliary lifting frame for highway electromechanical maintenance, which addresses the problems of cumbersome tool placement and retrieval and inconvenient inspection and maintenance of existing auxiliary lifting frames for highway electromechanical maintenance.

[0005] An auxiliary lifting frame for highway electromechanical maintenance includes a scissor lift and an auxiliary maintenance mechanism. The auxiliary maintenance mechanism includes a mounting slot, one end of which is fixedly connected to a U-shaped locking block. The U-shaped locking block is fitted onto the guardrail surface of the scissor lift, and one end of the U-shaped locking block is threadedly connected to a locking bolt. The shank of the locking bolt passes through the U-shaped locking block and contacts the guardrail of the scissor lift.

[0006] In one embodiment, the opening of the U-shaped card block faces downward, and there are two U-shaped card blocks.

[0007] In one embodiment, the U-shaped locking block and the locking bolt are used together in pairs, with the two U-shaped locking blocks and the two locking bolts symmetrically distributed on both sides of the center point of the mounting slot.

[0008] In one embodiment, a support column is fixedly connected to the bottom of the mounting slot, and the bottom of the support column contacts the standing plane of the scissor lift.

[0009] In one embodiment, the number of support columns is four, and the four support columns are respectively fixedly connected to the four bottom corners of the mounting slot box.

[0010] In one embodiment, a buffer pad, which is made of rubber material, is fixedly connected to the bottom of the support column.

[0011] In one embodiment, a positioning screw is threaded to the side end of the mounting slot, and the shank of the positioning screw extends into the interior of the mounting slot.

[0012] In one embodiment, the centerline of the positioning screw is parallel to the centerline of the locking bolt, and the positioning screw is disposed between two adjacent support columns. Beneficial effects

[0013] The aforementioned auxiliary lifting frame for highway electromechanical maintenance has a mounting slot that sets the tool operating height based on the fence height. The U-shaped locking block and locking bolt achieve horizontal fixation, and the four corner support columns, together with rubber buffer pads, ensure stability. The positioning screw adapts to the locking requirements of toolboxes of different sizes, effectively eliminating the need to bend over during operations such as replacing high-mast lights.

[0014] The forklift lift integrates a weight sensor, tilt alarm, and emergency accumulator with a fence protection system to monitor the load and platform level in real time. When the limit is exceeded, it automatically cuts off the hydraulic pressure and ensures emergency descent, greatly improving the safety of high-altitude operations. Attached Figure Description

[0027] The following is combined withFigures 1-4 This invention describes an auxiliary lifting frame for highway electromechanical maintenance.

[0028] In one embodiment, an auxiliary lifting frame for highway electromechanical maintenance includes: a scissor lift 100 and an auxiliary maintenance mechanism 200. The scissor lift 100 includes, but is not limited to, the following structures:

[0029] The scissor lift 100 consists of three main parts: an electric mobile chassis, a scissor lifting mechanism, and a fence protection system. The electric mobile chassis includes anti-slip tires, a travel motor, a gearbox, and a battery pack. The chassis frame is welded from channel steel and integrates a steering servo motor, enabling a ±90° steering angle. The scissor lifting mechanism consists of four sets of manganese steel cross arms hinged together by chromium-molybdenum alloy pins. Each set of scissor arms is equipped with roller guides to reduce friction. The hydraulic system uses double-acting cylinders in conjunction with a gear pump, and integrates a pilot-operated relief valve and a hydraulic lock in the oil circuit. The fence system includes a 1.2-meter-high galvanized pipe fence, a safety gate with magnetic locking, and a weight sensor and tilt alarm installed at the bottom of the platform.

[0030] The working principle of the scissor lift 100: When the equipment is running, the operator starts the travel motor through the waterproof control panel, which drives the tires to move via the gearbox. The steering motor receives commands via the CAN bus to adjust the direction of travel until the operator is directly below the equipment to be maintained. During the lifting phase, the motor drives the hydraulic pump to pressurize and deliver oil to the rodless chamber of the cylinder. The piston rod lifts the bottom scissor arm, and the platform is raised step by step until the operator is at a position where they can maintain the equipment. During descent, the solenoid directional valve switches the oil circuit, the cylinder returns oil under the weight of the platform, and the throttle valve controls the descent speed. The safety system monitors the load in real time (overload triggers shutdown when a preset value is reached), the platform level (hydraulic pressure is cut off when tilt exceeds the limit), and the fence status (lifting is prohibited if the door is not locked). In an emergency, the accumulator can provide emergency descent power.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the auxiliary maintenance mechanism 200 includes a mounting slot 210. One end of the mounting slot 210 is fixedly connected to a U-shaped locking block 220. The U-shaped locking block 220 is sleeved on the fence surface of the scissor lift 100. One end of the U-shaped locking block 220 is threadedly connected to a locking bolt 230. The rod of the locking bolt 230 passes through the U-shaped locking block 220 and contacts the fence of the scissor lift 100. The auxiliary maintenance mechanism 200 adopts a detachable design, which allows the staff to install the auxiliary maintenance mechanism 200 in a position that does not obstruct the staff according to the needs of the maintenance position, so as to reduce the impact of the auxiliary maintenance mechanism 200 on the staff maintaining the electromechanical equipment at height.

[0032] The opening of the U-shaped locking block 220 faces downward. There are two U-shaped locking blocks 220. The U-shaped locking blocks 220 and the locking bolts 230 are used in pairs. The two U-shaped locking blocks 220 and the two locking bolts 230 are symmetrically distributed on both sides of the center point of the mounting slot box 210. This can improve the locking effect of the mounting slot box 210, so that the auxiliary maintenance mechanism 200 can drive the toolbox to operate more stably at high positions.

[0033] The bottom of the mounting slot 210 is fixedly connected to a support column 240. The bottom of the support column 240 is in contact with the standing plane of the scissor lift 100. There are four support columns 240, which are fixedly connected to the four corners of the bottom of the mounting slot 210. This can prevent the mounting slot 210 from rotating or tilting during operation, and further improve the stability of the mounting slot 210.

[0034] A buffer pad 250 is fixedly connected to the bottom of the support column 240. The buffer pad 250 is a rubber material component, which can reduce the probability of the support column 240 colliding with the scissor lift 100's standing platform due to bumps during the movement of the scissor lift 100 driving the mounting box 210, thus ensuring the integrity of the scissor lift 100's standing platform.

[0035] The mounting slot 210 is threadedly connected to a positioning screw 260 on its side end. The shank of the positioning screw 260 extends into the interior of the mounting slot 210. The axis of the positioning screw 260 is parallel to the axis of the locking bolt 230. The positioning screw 260 is positioned between two adjacent support columns 240. The positioning screw 260 can not only securely lock the toolbox inside the mounting slot 210, but also lock toolboxes of different sizes to meet the locking requirements of different toolboxes, thereby expanding the overall practicality of the auxiliary maintenance mechanism 200.

[0036] Working principle: Before the scissor lift 100 is put into operation, the operator first opens the safety door on the scissor lift 100, moves the auxiliary maintenance mechanism 200 inside the enclosure, and then attaches the U-shaped locking block 220 to the corresponding position of the scissor lift 100 enclosure. The operator then manually rotates the locking bolt 230 until the locking bolt 230, together with the U-shaped locking block 220, clamps the scissor lift 100 enclosure. The operator can then place the toolbox inside the mounting slot 210 and manually rotate the positioning screw 260 in the corresponding direction. The positioning screw 260 causes the toolbox to abut against the vertical inner wall of the mounting slot 210, firmly locking the toolbox inside the mounting slot 210. When the operator is performing normal maintenance and repair of the electromechanical equipment at a height, the operator can access the toolbox without bending over, thus reducing the burden on the operator when maintaining the electromechanical equipment at a height.

[0037] It should be noted that the scissor lift 100 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs, and will not be elaborated here.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
