Description
Technical Field
[0001] This utility model relates to the field of flatbed truck technology, specifically to a flatbed truck with a reserved span across the south side. Background Technology
[0002] In industrial production, construction, and steel plate transshipment, flatbed trucks are commonly used as steel plate carrying and transportation equipment, and are widely used for cargo transfer in environments such as workshops, cross-regional factory areas, and construction sites. Reserved areas on the south side of the flatbed truck as specific nodes for steel plate turnover, temporary storage, and cross-regional transfer within industrial plants or construction sites place higher demands on the adaptability, safety, and practicality of these trucks.
[0003] When existing flatbed trucks are used in scenarios where the south side is reserved, traditional flatbed trucks are mostly simple planar load-bearing structures, lacking effective steel plate barriers and positioning devices. When transporting irregularly shaped steel plates, stacking steel plates, or when starting and stopping during track operation, the steel plates are prone to sliding, shifting, or even falling off, which may not only cause damage to the steel plates but also lead to safety accidents.
[0004] Because different types and sizes of steel plates have different support requirements for the load-bearing platform, the load-bearing structure of existing flatbed trucks is mostly fixed and cannot be flexibly adjusted according to the actual size and weight distribution of the steel plates. For steel plates that need to be placed at an angle or supported at a specific angle, there is a lack of corresponding adjustable support mechanisms.
[0005] The existing flatbed trailer on the south side of the reserved span was originally controlled by a wired handle. Personnel had to hold the handle and move alongside the trailer, and the power cord was only 2 meters long, meaning a safe distance of only 2 meters could be maintained between personnel and the trailer. However, due to the limited space between the north and south sides of the flatbed trailer, and the railings between the two spans, personnel had to move very close to the trailer, which was inconvenient. Furthermore, personnel needed to be highly concentrated, making them extremely vulnerable to collisions with the trailer or steel plates, posing a safety hazard.
[0006] Therefore, it is necessary to invent a planar vehicle that is reserved for crossing the south side to solve the above problems. Utility Model Content
[0007] The purpose of this utility model is to provide a pre-reserved flatbed truck for crossing the south side, so as to solve the above-mentioned shortcomings in the technology.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a pre-reserved flatbed vehicle for crossing the south side, including a frame, the upper surface of which is provided with a number of evenly distributed supports, the front of which is provided with a number of equally spaced slots, each slot having a cylinder horizontally fixedly installed therein, and the front of which is provided with a blocking mechanism. The blocking mechanism includes a U-shaped frame, with symmetrical through slots on both sides of the U-shaped frame. A shaft is provided inside the opening of the U-shaped frame, and the two ends of the shaft are respectively rotatably inserted into the through slots on both sides of the U-shaped frame. A roller is fixedly installed in the middle of the shaft, a connector is provided near the tail end of the U-shaped frame, a stop is provided above the U-shaped frame, the lower end of the stop is rotatably connected to the upper part of the U-shaped frame, and a connecting rod is rotatably installed on the back of the stop.
[0009] As a preferred embodiment of this utility model, each of the blocking mechanisms corresponds to a cylinder, the front end of the connector is movably sleeved on the shaft, the output end of the cylinder is fixedly connected to the back of the connector, the lower end of the linkage rod is movably sleeved on the shaft, and the roller, connector and linkage rod do not contact each other on the shaft.
[0010] As a preferred embodiment of this utility model, a plurality of evenly distributed pads are fixedly installed at the bottom of each bracket, and the height of each pad gradually increases in sequence. A plurality of evenly distributed protrusions are fixedly installed on the upper surface of the frame, and an insertion port is provided above the protrusions. The lower end of the bracket is inserted into the insertion port through the pads.
[0011] As a preferred embodiment of this utility model, a control box is fixedly installed at the lower end of one end of the vehicle frame, a guardrail is fixedly installed at the upper end of the other end of the vehicle frame, a warning light is fixedly installed at the upper end of the rear end of the guardrail, and a control panel is fixedly installed at the upper front end of the guardrail.
[0012] As a preferred embodiment of this utility model, the guardrail is L-shaped, and a metal plate is fixedly installed at the lower end of the other end of the vehicle frame. The front end of the metal plate is fixedly connected to the lower front end of the guardrail, and the control box is electrically connected to the control panel and the warning light respectively through wires.
[0013] As a preferred embodiment of this utility model, a steel plate is placed above several of the brackets, a baffle is fixedly installed on the front of the frame by bolts, a support plate is fixedly installed on the front of the baffle, the blocking mechanism is fixedly arranged on the upper surface of the support plate, and the U-shaped frame is fixedly installed on the support plate.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: By setting multiple sets of blocking mechanisms on the front of the frame and linking them with cylinders, the cylinders drive the connecting parts to move the shaft along the through groove of the U-shaped frame, which in turn drives the linkage rod to simultaneously pull the stop block to flip, realizing the automatic opening and closing of the stop block. When closed, the stop block can effectively block the steel plate on the frame. With the evenly distributed blocking mechanism layout, it can comprehensively restrict the sliding and displacement of the steel plate from the front. The bottom of the designed bracket adopts a pad design with progressively increasing height. With the insertion structure of the protrusion on the frame, the mounting angle and position of the bracket can be adjusted to form a bearing surface with different inclinations to meet the special bearing scenarios of tilted steel plates.
[0015] By installing an L-shaped safety barrier, both safety protection for operators and structural stability are enhanced by the metal plate. The integrated control panel, combined with the intelligent control box, allows for quick start / stop of the barrier mechanism and quick stopping of the flatbed cart, reducing operational complexity. Warning lights on the safety barrier provide real-time alerts as the flatbed cart moves, effectively reminding nearby personnel to avoid the area. The added metal plate allows operators to stand, facilitating synchronized movement with the flatbed cart and preventing the risk of injury from collisions with the steel plate or the cart itself.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0020] This utility model provides, for example Figure 1-9 The above-mentioned pre-reserved flatbed truck includes a frame 1. The upper surface of the frame 1 is provided with several evenly distributed supports 3. The front of the frame 1 is provided with a number of equally spaced slots 11. Each slot 11 is horizontally fixedly installed with a cylinder 14. The front of the frame 1 is provided with a blocking mechanism 7. In this embodiment, the frame 1 serves as the overall skeleton of the equipment. Rollers 74 and other control and drive components are installed at its bottom, while the equally spaced slots 11 on its front precisely fix the cylinders 14, ensuring that multiple sets of blocking mechanisms 7 operate synchronously to meet the heavy-load transportation requirements.
[0021] The blocking mechanism 7 includes a U-shaped frame 71, with symmetrical through slots 72 on both sides of the U-shaped frame 71. A shaft 73 is provided in the opening of the U-shaped frame 71, and the two ends of the shaft 73 are respectively rolled into the through slots 72 on both sides of the U-shaped frame 71. A roller 74 is fixedly installed in the middle of the shaft 73. A connector 75 is provided near the tail end of the U-shaped frame 71. A stop 77 is provided above the U-shaped frame 71. The lower end of the stop 77 is rotatably connected to the upper part of the U-shaped frame 71. A connecting rod 76 is rotatably installed on the back of the stop 77.
[0022] Furthermore, in the above technical solution, each blocking mechanism 7 corresponds to a cylinder 14, the front end of the connecting piece 75 is movably sleeved on the shaft 73, the output end of the cylinder 14 is fixedly connected to the back of the connecting piece 75, the lower end of the linkage rod 76 is movably sleeved on the shaft 73, and the roller 74, the connecting piece 75 and the linkage rod 76 do not contact each other on the shaft 73.
[0023] In this embodiment, the U-shaped frame 71 in the barrier mechanism 7 has symmetrical through slots 72 on both sides to provide a fixed sliding track for the shaft 73, preventing the shaft 73 from shifting and causing protection failure; it also provides a protective shell for internal components, reducing external collision damage and maintaining a compact structure. Furthermore, the shaft 73 provides a mounting carrier for the roller 74, connector 75, and linkage rod 76, transmitting the driving force of the cylinder 14 and driving the various components to move in tandem.
[0024] When cylinder 14 outputs driving force, shaft 73 transmits power to connector 75 and connecting rod 76, causing stop block 77 to rotate smoothly, thereby blocking or unloading the sheet material placed on the flatbed.
[0025] When the stop block 77 is closed (i.e., in the vertical state), it effectively blocks the steel plate 4 from the front, limiting sliding and offset, and preventing equipment start-up and shutdown, and material falling. The flip-type structure opens during loading and unloading (i.e., the stop block 77 is in the horizontal state), which does not obstruct material discharge, balancing protection and ease of operation.
[0026] Furthermore, in the above technical solution, each bracket 3 has multiple evenly distributed pads fixedly installed at its bottom, and the height of each pad gradually increases. Several evenly distributed protrusions 2 are fixedly installed on the upper surface of the frame 1, and an insertion port is provided above the protrusions 2. The lower end of the bracket 3 is inserted into the insertion port through the pads.
[0027] In this embodiment, the slot above the protrusion 2 provides a detachable and adjustable installation interface for the bracket 3, allowing for easy assembly and disassembly without the need for specialized tools. The evenly distributed design, together with the bracket 3, forms multi-point support, distributing the weight of the steel plate 4 and protecting the material and the frame 1 structure. During transportation, the multi-point support formed by the protrusion 2 and the bracket 3 ensures that the steel plate 4 is subjected to uniform force, significantly improving its adaptability and flexibility.
[0028] The foot design with progressively increasing height at the bottom of the bracket 3 can be adjusted to create bearing surfaces with different inclinations, adapting to curved steel plates 4 and special steel plates 4 with slope requirements; the evenly distributed layout works in conjunction with the protrusions 2 to stably support the steel plates 4 and prevent shaking during transportation.
[0029] Furthermore, in the above technical solution, a control box 5 is fixedly installed at the lower end of one end of the frame 1, a guardrail 6 is fixedly installed at the upper end of the other end of the frame 1, a warning light 61 is fixedly installed at the upper end of the rear end of the guardrail 6, and a control panel 63 is fixedly installed at the upper front end of the guardrail 6.
[0030] Furthermore, in the above technical solution, the guardrail 6 is in the shape of an L-shape, and a metal plate 62 is fixedly installed at the lower end of the other end of the frame 1. The front end of the metal plate 62 is fixedly connected to the lower front end of the guardrail 6. The control box 5 is electrically connected to the control panel 63 and the warning light 61 respectively through wires.
[0031] In this embodiment, the control box 5 serves as the control core, integrating and transmitting control signals to control the start and stop of the barrier mechanism 7 and the running status of the flatbed truck. The L-shaped structure of the guardrail 6 prevents operators from accidentally approaching the danger zone, avoiding safety accidents caused by the slippage of the steel plate 4 or equipment collisions. It provides a stable mounting platform for the warning light 61 and the control panel 63, ensuring that the operation and warning devices are positioned reasonably for easy observation and operation.
[0032] Warning light 61 emits a clear audible and visual warning when the equipment is running, alerting nearby personnel to avoid the area and reducing the risk of collisions in confined spaces and crowded environments. Warning light 61 is linked to control box 5, using different light states to provide feedback on equipment operation and malfunction status, facilitating timely detection of abnormalities.
[0033] The metal plate 62 is connected and fixed to the frame 1 and the guardrail 6, enhancing the structural stability of the metal plate 62 and providing a standing platform for operators. This solves the problem of traditional equipment requiring operators to hold a short power cord handle while running, maintaining a safe distance from the equipment and avoiding the risk of collision. The control panel 63 integrates function buttons for equipment start / stop and barrier mechanism 7 control, and its installation position is convenient for operators to stand while operating, improving comfort and safety.
[0034] Furthermore, in the above technical solution, a steel plate 4 is placed above several brackets 3, a baffle 12 is fixedly installed on the front of the frame 1 by bolts, a support plate 13 is fixedly installed on the front of the baffle 12, a blocking mechanism 7 is fixedly installed on the upper surface of the support plate 13, and a U-shaped frame 71 is fixedly installed on the support plate 13.
[0035] In this embodiment, cylinder 14 provides a stable driving force, causing the blocking mechanism 7 to open and close automatically without manual operation. Baffle 12 prevents external debris and dust from entering the frame 1, protecting components such as cylinder 14 and extending their service life. Support plate 13 provides a flat mounting surface for the blocking mechanism 7, ensuring accurate installation. Multiple through holes on the front of baffle 12 correspond to the positions of each cylinder 14, with the output end of cylinder 14 passing through the corresponding through hole, thus preventing cylinder 14 from jamming during operation.
[0036] The working process of the pre-reserved south-side flatbed truck provided by this utility model is as follows: Operate the control panel 63, start the cylinder 14 to control the blocking mechanism 7, so that the stop block 77 is in a vertical state, and then place the steel plate 4 to be transferred steadily on the bracket 3, ensuring that the steel plate 4 is placed neatly and does not exceed the load-bearing capacity of the frame 1.
[0037] If the operator needs to follow the vehicle, the operator must stand on the metal plate 62 and hold the guardrail 6 (an anti-slip mat can be added to the upper surface of the metal plate 62 to increase the anti-slip effect and facilitate the operator's standing). The operator controls the flatbed vehicle to move forward and backward along the pre-laid and fixed track through the control panel 63, and adjusts the running speed. The operator then follows the equipment synchronously on the metal plate 62, maintaining a safe operating distance.
[0038] Once the designated location is reached, the control panel 63 stops the flatbed truck from running and turns off the warning light 61; the start cylinder 14 opens the stop block 77, making the stop block 77 horizontal. If the bracket 3 is tilted at this time, when the stop block 77 is opened, the steel plate 4 will slide directly off the smooth upper surface of the bracket 3.
[0039] If the bracket 3 is in a horizontal position, after the stop 77 is opened, the steel plate 4 on the frame 1 needs to be removed smoothly by a forklift or other machinery.
[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
