Description

Technical Field

[0001] This utility model relates to the field of installation and dismantling equipment, specifically a bridge anti-collision guardrail template installation and dismantling equipment. Background Technology

[0002] In highway and bridge construction, it is common to encounter situations requiring the laying or construction of long-distance cast-in-place concrete structures. These structures often include bridge crash barriers, road medians, and slope protection structures. Casting formwork is required when pouring these concrete structures. These structures not only need to possess high stability and durability during use, but also must ensure efficient, safe, and precise installation and dismantling after construction.

[0003] For the installation and removal of formwork for cast-in-place concrete structures, traditional construction methods largely rely on hoisting operations. Especially when dealing with relatively light formwork that requires precise placement and removal, cranes become indispensable. In practice, 8-ton cranes are typically chosen for these operations because they can meet the hoisting needs of most small formwork units while maintaining relatively low operating costs and operational efficiency. However, cranes have limited coverage areas for fixed-point hoisting, require multiple movements during formwork installation and removal, and are difficult to maneuver in narrow areas, resulting in low efficiency and limited flexibility. Therefore, a method or equipment capable of solving these problems is needed. Utility Model Content

[0007] Furthermore, a sliding bracket is provided at the front end of the fixed vehicle body section, and the hoisting assembly slides against the sliding bracket.

[0008] Further, the hoisting assembly comprises a hoisting arm, a winch and a pulley mechanism, the winch is arranged on the sliding car body section, and the pulley mechanism is arranged on the hoisting arm.

[0009] Further, the pulley mechanism comprises a first fixed pulley, a second fixed pulley, a movable pulley and a sling, the first fixed pulley and the second fixed pulley are connected to the hoisting arm, one end of the sling is connected to the hoisting arm, the other end of the sling passes through the first fixed pulley and the second fixed pulley and is connected to the winch, the movable pulley is arranged on the sling in a sliding mode, and the movable pulley and the first fixed pulley form a labor-saving pulley structure.

[0010] Further, the steering wheel is provided with a steering handle for controlling the movement direction of the car body frame.

[0011] Further, the rear end of the fixed car body section is hinged with a car body handrail.

[0012] The beneficial effects of the utility model are as follows: the telescopic structure of the fixed car body section and the sliding car body section enables the machine to adjust the length of the car body according to the actual situation of the construction site, can be more conveniently moved in a narrow construction space, the single steering wheel is rear-mounted, the operation of flexible movement of the car body is more convenient, therefore, the equipment is suitable for small and medium-sized template installation and dismounting construction in engineering, can be randomly walked during hoisting, saves the mechanical use cost of the crane, has high flexibility and high construction efficiency.

[0016] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific implementation mode, structure, features and effects of the utility model are described in detail as follows in combination with the drawings and the preferred embodiments.

[0017] As Figure 1The utility model discloses a bridge anti -collision guard rail formwork installs and dismantles machine tool, including frame car body 2 and hoisting assembly, frame car body 2 includes fixed car body section and sliding car body section, be provided with single steering wheel 4 on fixed car body section, be provided with two fixed wheels 3 on sliding car body section, sliding car body section is slidably arranged on fixed car body section, and one end of hoisting assembly is hinged on sliding car body section, and hoisting assembly is slidably contacted on fixed car body section, and hoisting assembly is lifted along with the sliding telescopic of sliding car body section on fixed car body section,

[0018] Because in partial narrow construction space, the size of crane is big, is difficult to reach through crane, and needs to adjust position when driving at construction position, and when removing the formwork of concrete pouring, needs to remove piece by piece, namely needs to move to remove after removing a place, thus when reaching a position to remove, need to adjust crane, and due to the low flexibility of crane, lead to the reduction of work efficiency.

[0019] And in the embodiment, the front end of fixed car body section is provided with sliding support 9, and hoisting assembly is slidably contacted on sliding support 9;The telescopic structure of fixed car body section and sliding car body section makes that installation and removal machine tool can adjust the length of its car body according to the actual situation of construction site, and the sliding support 9 of the front end of fixed car body section is perpendicular to horizontal plane, and it is used as the support structure of hoisting assembly on sliding car body section, and hoisting assembly is hinged with sliding car body section, and due to the invariable height of sliding support 9, when the hinge point of sliding car body section and hoisting assembly slides away from sliding support 9, the height of hoisting assembly is reduced, and its gravity center is also low, and the length of car body is also shortened, and it can be more convenient to move in narrow construction space, and after reaching the hoisting position, the hinge point of sliding car body section and hoisting assembly slides close to sliding support 9, hoisting assembly height is raised, and the length of car body is extended, and hoisting operation can be carried out.

[0020] The advantages of rear-wheel steering over front-wheel steering mainly lie in the following aspects: improved flexibility: Rear-wheel steering allows the device to move more flexibly in narrow spaces. Especially in situations that require precise control, rear-wheel steering can significantly reduce the turning radius of the device, making it easier to navigate and work in these areas. Optimized space utilization: For some mobile control devices that need to operate efficiently in limited space, rear-wheel steering can improve their space utilization. The rear-wheel steering device can more easily access goods, thereby improving the efficiency of installation and removal. Improved control performance: Rear-wheel steering helps improve the overall control performance of the device. At high speeds, the rear wheels can rotate in the same direction as the front wheels, enhancing the stability of the device; at low speeds or when precise control is needed, the rear wheels can rotate in the opposite direction of the front wheels, reducing the turning radius and improving flexibility. This combination of flexibility and stability allows the device to perform well in various working conditions. Reduced tire wear: In some cases, rear-wheel steering can reduce tire wear. For example, in situations where the device needs to turn frequently, rear-wheel steering can reduce the friction area of the tire with the ground, thereby reducing the wear rate of the tire. This helps to extend the service life of the tire and reduce maintenance costs.

[0021] Therefore, the device is suitable for small template installation and removal construction in engineering, can walk freely during hoisting, saves the mechanical use cost of the crane, has high flexibility, and has high construction efficiency.
