Description

Technical Field

[0001] This utility model belongs to the field of transport vehicle technology, and in particular relates to a small trolley for manual short-distance transport of curb stones. Background Technology

[0002] Curbstones are marker stones placed between the road surface and other structures. They are generally required between the median strip and the road surface, and between the sidewalk and the road surface in urban roads. They are also commonly found at the edges of the central median strip, the right edge of the driving lane, or the outer edge of the shoulder on highways. Traditionally, curbstone transportation and installation involve using construction machinery, which results in low equipment utilization, high construction costs, and significant site occupation and disruption. Manual lifting and moving of curbstones is also labor-intensive and inefficient.

[0003] In summary, it is necessary to develop and design an auxiliary facility for short-distance transport of curb stones during curb stone construction in order to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a short-distance manual transport vehicle for curb stones, which has a simple structure and is easy to operate, assisting manual transport of curb stones over short distances, reducing manpower consumption and improving work efficiency.

[0005] The technical solution adopted by this utility model is as follows: a short-distance manual transport trolley for curb stones, including an inclined handrail, a frame upright installed at the front end of the inclined handrail, a frame crossbar installed between the top of the frame upright, a wheel support frame installed on the outer side of the two frame uprights, and a wheel installed between the lower end of the frame upright and the wheel support frame on the same side via an axle; a hanger lug is installed at the bottom middle of the frame crossbar, and a clamping and hanging device is installed on the hanger lug, the clamping and hanging device including a middle horizontal arm, the middle part of the middle horizontal arm is hinged to the hanger lug, side arms are installed at both ends of the middle horizontal arm using pins, a clamping plate is installed at the lower outer end of the two side arms, and an anti-slip rubber plate is installed on the inner side wall of the clamping plate.

[0006] Preferably, a clamping plate reinforcing rib is welded and installed between the outer facade of the clamping plate and the bottom of the outer end of the side forearm.

[0007] Preferably, the hanger lug includes two opposing lugs, the upper ends of which are welded and fixed to the bottom of the middle part of the frame crossbar. Pin holes are provided on both lugs and in the middle of the middle horizontal arm. The middle part of the middle horizontal arm is located between the two lugs of the hanger lug and a pin is inserted therethrough.

[0008] Preferably, a frame diagonal support is installed between the two ends of the frame crossbar and the frame upright. The upper end of the frame diagonal support is welded and fixed to the frame crossbar, and the lower end is welded and fixed to the frame upright.

[0009] Preferably, a handrail crossbar is installed between the rear ends of the inclined handrails, and a horizontal handrail is installed at the rear end of each inclined handrail.

[0010] Preferably, a reinforcing brace is installed between the two frame uprights and the diagonal handrails behind them, with the upper end of the reinforcing brace welded to the frame upright and the lower end welded to the diagonal handrail.

[0011] The advantages and positive effects of this utility model are:

[0012] This utility model provides a manual short-distance transport trolley for curb stones, applicable to curb stone construction scenarios. It replaces existing large transport machinery and assists manual transport of curb stones over short distances. The trolley is equipped with a clamping and hanging device. The clamping plates and anti-slip rubber plates at the ends of its side arms clamp and fix the curb stones. Under the weight of the curb stones, the three-arm structure (one central horizontal arm and two side arms) of the clamping and hanging device can stably clamp and hang the curb stones.

[0013] The slanted handrail, frame uprights, and frame crossbars form a lever structure with the contact point between the wheels and the ground as the fulcrum. Therefore, by pressing down on the slanted handrail, the clamping and hanging device and the curbstone in front can be lifted. After lifting, the trolley can be pushed to move the curbstone. Once at the target location, lifting the slanted handrail will lower the curbstone to the ground and release the clamping and hanging device from the curbstone. This transport trolley has a simple structure and is easy to operate, effectively assisting manual labor in short-distance transport of curbstones, reducing manpower consumption and improving work efficiency.

Detailed Implementation

[0021] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0022] Please see Figure 1 and Figure 2 The present invention relates to a short-distance manual transport trolley for curb stones, comprising an inclined handrail 3, a frame upright 4 installed at the front end of the inclined handrail 3, a frame crossbar 6 installed between the top of the frame upright 4, a wheel support frame 7 installed on the outer side of the two frame upright 4, and a wheel 8 installed between the lower ends of the frame upright 4 and the wheel support frame 7 on the same side via an axle 9.

[0023] The frame crossbar 6 connects the two frame uprights 4 to form a whole. To improve structural strength, in this embodiment, frame diagonal supports 10 are installed between the two ends of the frame crossbar 6 and the frame uprights 4. The upper end of the frame diagonal supports 10 is welded to the frame crossbar 6, and the lower end is welded to the frame uprights 4. Therefore, the two frame uprights 4, the frame crossbar 6, and the two frame diagonal supports 10 constitute a portal structure.

[0024] like Figure 2 As shown, the wheel support frame 7 includes an upper diagonal brace and a lower vertical beam. The upper end of the diagonal brace is welded and fixed to the upper end of the frame upright 4. A connecting beam is welded and installed between the upper part of the vertical beam and the middle part of the frame upright 4, thus forming a space for accommodating the wheel 8 between the lower part of the vertical beam and the lower part of the frame upright 4. The wheel 8 is installed in this space using a wheel axle 9.

[0025] In this embodiment, a reinforcing brace 5 is installed between the two frame uprights 4 and their respective rear diagonal handrails 3. The upper end of the reinforcing brace 5 is welded to the frame upright 4, and the lower end is welded to the diagonal handrail 3, which improves the overall structural strength of the transport trolley. The diagonal handrails 3, frame uprights 4, and frame crossbars 6 constitute a lever structure with the contact point between the wheel 8 and the ground as the fulcrum. In this embodiment, a handrail crossbar 2 is installed between the rear ends of the diagonal handrails 3, and a horizontal handrail 1 is installed at the rear end of each diagonal handrail 3. The handrail crossbar 2 is used to combine the two diagonal handrails 3 into one, improving the overall structural strength. The horizontal handrail 1 and the diagonal handrail 3 can be made by bending the same steel pipe. During operation, the operator holds the horizontal handrail 1 with both hands.

[0026] A hanger lug 11 is installed at the bottom center of the crossbar 6 of the frame. A clamping and hanging device is installed on the hanger lug 11. The clamping and hanging device is used to clamp and hang the curb stone 18.

[0027] Please see Figure 3 It can be seen that:

[0028] The clamping and hanging device includes a central horizontal arm 12, the middle of which is hinged to a hanger lug 11. Side arms 13 are mounted at both ends of the central horizontal arm 12 using pins 14. Clamping plates 15 are mounted on the lower outer ends of the two side arms 13. Anti-slip rubber plates 16 are mounted on the inner sidewalls of the clamping plates 15. To improve structural strength, in this embodiment, clamping plate reinforcing ribs 17 are welded and installed between the outer facade of the clamping plates 15 and the bottom outer ends of the side arms 13. The central horizontal arm 12 and the two side arms 13 form a three-arm structure. The curbstone 18 is stably clamped between the two clamping plates 15 and the anti-slip rubber plates 16 under its own weight and the friction provided by the anti-slip rubber plates 16.

[0029] In this embodiment, the hanger lug 11 includes two opposing lugs. The upper ends of the two lugs are welded and fixed to the bottom of the middle part of the frame crossbar 6. Pin holes are provided on both lugs and in the middle of the intermediate horizontal arm 12. The middle part of the intermediate horizontal arm 12 is located between the two lugs of the hanger lug 11 and a pin 14 is inserted through it. Since the intermediate horizontal arm 12 of the clamping and hanging device is hinged to the hanger lug 11 by the pin 14, the clamping and hanging device remains horizontal under the aforementioned portal structure regardless of the posture of the main body of the transport trolley.

[0030] Operating instructions:

[0031] Figure 4The diagram shows the structure of the transport trolley when lifting and lowering the curbstone 18. When the horizontal handrail 1 and the diagonal handrail 3 are fully raised, the front clamping and lifting device is lowered. The operator fully opens the two side arms 13 of the clamping and lifting device, positioning the top of the curbstone 18 between the two sets of clamping plates 15 and the anti-slip rubber plate 16. Then, pressing down on the horizontal handrail 1 and the diagonal handrail 3, the lever structure lifts the front clamping and lifting device upwards, simultaneously clamping the curbstone 18. At this point, the transport trolley and the curbstone 18 transform into... Figure 5 As shown in the transportation state, the bottom of the curbstone 18 is lifted off the ground to a certain height, and the transport trolley is in a pushcart state. At this time, the operator can push and move the transport trolley. After it is moved into place, the operator raises the horizontal handrail 1 and the diagonal handrail 3, lowers the clamping and hanging device, and places the curbstone 18 on the ground. Then the operator manually opens the side forearm 13 upwards, and the two sets of clamping plates 15 and anti-slip rubber plates 16 release the curbstone 18. After that, the transport trolley is moved to another position and prepared for the next short-distance relocation operation.
