[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0019] This application provides a multi-functional beam end work trolley, which can solve the technical problem of low efficiency in beam end operations in the prior art.

[0020] Figure 1 This is a front view of a beam-end multi-functional work platform provided in an embodiment of this application. Figure 2 This is a side view of a beam-end multi-functional work platform provided in an embodiment of this application.

[0021] See also Figure 1 and Figure 2 This application provides a beam-end multi-functional work platform trolley including: a mobile chassis 1; a construction platform 2 located on the mobile chassis 1, with a support cylinder 3 for abutting against the beam end at one end of the construction platform 2 away from the mobile chassis 1, the construction platform 2 including a construction surface facing the beam end, wherein the construction surface is provided with a roughening component 4 for roughening the beam end, and a transverse moving component is provided between the construction surface and the roughening component 4 for realizing the roughening component 4 moving in the transverse direction on the construction platform 2; and a lifting platform 5 symmetrically arranged on both sides of the mobile chassis 1, and the lifting platform 5 is slidably connected to the construction platform 2, with inclined supports 6 provided on both sides of the lifting platform 5 for fixing the position of the lifting platform 5 relative to the position of the construction platform 2.

[0022] Specifically, the mobile chassis 1 serves as the load-bearing foundation for the entire work platform, integrating components such as the construction platform 2, the roughening assembly 4, and the lifting platform 5 to achieve overall mobility. Once the work platform moves to the designated position, the support cylinder 3 extends, ensuring close contact between the construction platform 2 and the beam end, forming a stable support and guaranteeing the stability of the construction platform 2 during roughening and tensioning operations. Simultaneously, the top of the construction platform 2 is equipped with a two-way self-locking hand-cranked winch, which can be tightened with the reinforcing steel at the top of the beam during operation to prevent tipping.

[0023] Meanwhile, a traveling motor 12 is installed on the top of the trolley, and an electric hoist is suspended from the traveling motor 12. A jack 11 is installed at the bottom of the trolley. The jack 11 is firmly connected to the hook of the electric hoist. When the traveling motor 12 is started, the trolley is driven to move along the track in a predetermined direction by controlling the forward and reverse rotation of the traveling motor 12. This drives the electric hoist and the jack 11 to move vertically or horizontally to the designated position. In this way, the trolley can achieve precise positioning of the jack 11.

[0024] After the lifting platform 5 is adjusted to a suitable height, the inclined support 6 extends and presses against the ground to ensure the stability of the lifting platform 5. Furthermore, the lifting platform 5 is located at its lowest point during the movement of the work trolley to ensure safety during movement. The lifting platform is equipped with a fall arrestor to ensure safety when the platform is used for construction at height.

[0025] Driven by the lateral movement component, the chiseling component 4 can flexibly adjust its lateral position on the construction platform 2 according to the specific location of the beam end and the chiseling requirements, so as to realize the chiseling operation of different areas of the beam end, ensuring the comprehensiveness and accuracy of the chiseling work. At the same time, the construction personnel can directly control the movement of the chiseling component 4 through the controller, making the construction process safer and more convenient.

[0026] The multi-functional beam-end work trolley provided in this application embodiment can achieve automated and coordinated control of two key processes: precise jack positioning, assisted installation, and automatic tensioning. This significantly saves manpower, improves tensioning efficiency, and further enhances the safety of tensioning operations. Two tensioning trolleys are used as a set, suitable for tensioning operations at both ends of railway box girders.

[0027] In this embodiment, the construction platform 2 includes: a support frame vertically mounted on the mobile chassis 1, and multiple construction platforms 7 sequentially mounted on the support frame in the longitudinal direction, wherein each construction platform 7 is slidably connected to the support frame in a direction away from or close to the construction surface.

[0028] Specifically, the heights of the construction platforms 7 are 2m, 3.5m, 5m, and 6.3m. The construction platforms 7 can be extended and reversed, allowing construction workers to easily adjust their extended or retracted state, as well as their orientation, to obtain the optimal working angle and operating space according to actual operational needs. Furthermore, in this embodiment, each construction platform 7 is equipped with guardrails 8 on both sides to ensure workers can work safely and efficiently at various heights.

[0029] Construction platform 7 is equipped with an externally powered vehicle-mounted electrical control box, a pump station electrical control box, and tensioning equipment. It also features two 220V sockets for charging the tensioning equipment and powering tools such as on-site cutting machines. Outdoor lighting is also provided for nighttime tensioning operations. Electrical wires and pipes are installed within cable trenches to ensure a tidy construction platform 7.

[0030] In this embodiment, the lateral movement component includes: a slide rail and a slider slidably connected to the slide rail. The slider has a mounting groove, and a telescopic member for moving the roughening component 4 away from or near the construction surface is mounted in the mounting groove. One end of the telescopic member moves in the mounting groove in the direction away from or near the construction surface, and the other end of the telescopic member is rotatably connected to the roughening component 4. A first slide rail is provided on the side of the mounting groove facing the telescopic member, and a second sliding member matching the slide rail is provided on the outer wall of the telescopic member.

[0031] A rotary component is provided between the telescopic component and the chiseling assembly 4 to enable the other end of the telescopic component to rotate or be relatively fixed to the chiseling assembly 4. One end face of the rotary component is fixedly connected to the telescopic component, and the other end face of the rotary component is rotatably connected to the chiseling assembly 4. The chiseling assembly 4 rotates or is fixed around the rotary component.

[0032] When it is necessary to perform chiseling operations at a specific angle on the beam end face, the chiseling component 4 can be rotated around the axis of the rotating component to the required angle by controlling the rotating component, and then the chiseling operation is performed, thereby realizing chiseling treatment of the beam end face in all directions and at multiple angles, ensuring the uniformity and thoroughness of chiseling.

[0033] Furthermore, when roughening is not required, the roughening component 4 retracts into the trolley through the cooperation of the rotating component and the telescopic component, without affecting other processes such as prestressed steel strand tensioning. When roughening is required, the roughening component 4 extends to the working position through the extension action of the telescopic component. Construction personnel can control the rotation, lateral movement, and lifting of the roughening component 4 via remote control to achieve all-round roughening treatment of the beam end face. At the same time, through remote control operation, construction personnel can quickly complete the roughening operation from a safe position, improving construction efficiency.

[0034] In this embodiment of the application, a longitudinal moving component is provided between the rotary component and the chiseling component 4 to enable the chiseling component 4 to move in the longitudinal direction. The longitudinal moving component includes a second slide and a second sliding member that matches the second slide. The end face of the second slide away from the second sliding member is rotatably connected to the rotary component, and the end face of the second sliding member away from the second slide is fixedly connected to the chiseling component 4.

[0035] During the roughening operation, the roughening component 4 moves longitudinally under the action of the longitudinal movement component, thereby enabling roughening treatment at different longitudinal positions on the beam end face. This not only improves the efficiency of the roughening operation but also enhances the adaptability of the roughening component 4 to beam ends with complex shapes.

[0036] In this embodiment, the chiseling assembly 4 includes: a first fixing plate and second fixing plates disposed on both sides of the first fixing plate. A chiseling head for chiseling the beam end is fixedly connected at the gap between the two second fixing plates. A laser rangefinder for measuring the distance between the chiseling head and the beam end is disposed on the side of the first fixing plate facing the chiseling head. A shock absorber is sandwiched between the first fixing plate and the second sliding member.

[0037] Specifically, the laser rangefinder can measure the distance between the chisel head and the beam end in real time, thereby ensuring that the chisel head maintains proper contact with the beam end during operation. This avoids poor chiseling results due to excessive distance or excessive damage to the beam end due to excessive distance. During the chiseling operation, the high-frequency impact between the chisel head and the beam end generates significant vibration. The shock absorber effectively buffers and absorbs these vibrations, protecting the chiseling assembly 4 and other related components from vibration damage, while improving the stability and accuracy of the chiseling operation. The chisel head can be a three-head pneumatic chiseling machine.

[0038] In this embodiment of the application, elastic support legs are installed on both sides of the second slide rail. One end of the elastic support leg is fixedly connected to the second slide rail, and the other end of the elastic support leg abuts against the beam end.

[0039] During the chiseling operation, the other end of the elastic support leg abuts against the beam end. Through its own elastic deformation capability, it can closely fit the beam end surface, thereby ensuring the stability of the entire chiseling frame during the operation.

[0040] In this embodiment, a guide rail bracket 9 is provided between the lifting platform 5 and the mobile chassis 1. One end face of the guide rail bracket 9 is fixedly connected to the mobile chassis 1, and the other end face of the guide rail bracket 9 is slidably connected to the lifting platform 5.

[0041] The lifting platform 5 can move up and down stably along the guide rail bracket 9. The guide rail bracket 9 provides a precise guiding path for the lifting platform 5, ensuring that the lifting platform 5 remains stable during the rising or falling process and will not shake or deviate.

[0042] In this embodiment, the construction platform 2 also includes a fixed surface opposite to the construction surface, and a protective plate 10 is fixedly connected to the fixed surface.

[0043] Specifically, the fixed surface is equipped with two layers of protective plates 10, one wooden and one steel, with openings corresponding to the channels to facilitate the smooth passage of the steel strands during the threading process. The protective plates 10 play an important protective role, preventing debris or equipment from falling from the rear of the trolley during construction and causing injury to construction personnel and equipment. At the same time, the opening design ensures the smooth progress of the threading operation, reflecting the rationality and practicality of the structural design.

[0044] This embodiment of the application is equipped with a chiseling component for chiseling operations. Simultaneously, the stable structure of the construction platform located on the mobile chassis provides a reliable platform for prestressed steel strand tensioning operations, integrating chiseling and tensioning functions. This embodiment avoids the need for switching between chiseling and tensioning equipment in traditional construction, eliminating the need for construction personnel to switch between different devices, thus improving work efficiency and ensuring construction continuity. Furthermore, construction personnel can easily adjust the position of the chiseling component on the construction platform, and the lateral movement component allows it to move laterally to adapt to different chiseling areas. The lifting platform is height-adjustable and can be fixed in position to meet the requirements of different beam heights and operating angles. The mobile chassis facilitates the rapid movement of the entire trolley to different construction positions, significantly improving operational flexibility and convenience. This embodiment of the application not only improves work efficiency but also ensures operational safety, providing a safe construction environment and reducing safety risks.
