Description

Technical Field

[0001] The utility model relates to the field of bucket trucks, in particular to a construction material transport trolley used for non-standard road sections. Background Art

[0002] During the garden construction process, it is necessary to build pavilions and other places for tourists to rest in the garden according to the plan. Therefore, staff are required to disperse and transfer the construction materials from the outside of the garden to different locations in the garden.

[0003] In the garden, except for the main road, which is relatively wide, the other auxiliary roads are relatively small, mainly to provide tourists with a good playing experience and let them feel the leisure time of the secluded paths. However, such a small road (which does not meet the road standards) is not conducive to the passage of transfer vehicles, so bucket trucks are needed to complete the transfer of construction materials.

[0004] At present, there are many types of bucket trucks on the market, such as a bucket truck disclosed in a Chinese patent with patent publication number CN203450145U, which includes a bucket, a frame, wheels and an axle, the front end of the bucket is hinged to the front end of the frame, and a support rod is provided at the rear of the bucket. When the bucket is in the retracted position, the support rod and the support portion formed by the extension of the frame are supported against each other, etc. Another example is a spring bucket truck disclosed in a Chinese patent with patent publication number CN203344975U, which is mainly composed of a frame, a bucket, an axle and wheels; the bucket is fixed to the frame with screws, the wheels are installed at both ends of the axle, and finally the axle is installed on the other side of the frame, that is, the opposite side of the bucket.

[0005] Whether it is the bucket cart provided by the above patent or other types of bucket carts, the spacing between the two running wheels is fixed, that is, it cannot be adjusted according to demand. This will cause a problem. When using the bucket cart to transfer materials in the garden, because the garden auxiliary road is narrow and the edge is paved with a zigzag road edge, if the spacing between the running wheels is greater than the width of the auxiliary road, the material cannot be transferred by the bucket cart. In order to achieve material transfer, it is necessary to move the material manually, which increases the labor intensity of the staff. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, a construction material transport trolley for non-standard road sections includes a bucket 1, a support mechanism 2 and an adjustment and fixing mechanism 3. The support mechanism 2 and the adjustment and fixing mechanism 3 are both arranged below the bucket 1. The support mechanism 2 is arranged below the adjustment and fixing mechanism 3, and the position of the support mechanism 2 relative to the bucket 1 can be adjusted by changing the state of the adjustment and fixing mechanism 3. Travel wheels 12 are arranged on both sides of the bucket 1. The two travel wheels 12 are respectively sleeved on the two ends of the support mechanism 2, and the support mechanism 2 can change its own length according to demand, so that the travel wheels 12 are located directly below the bucket 1, and the distance between the two travel wheels 12 is reduced, so that it can adapt to narrower roads, provide convenience for workers to move construction materials, and reduce labor intensity. Two legs 13 are provided at the lower end of the bucket 1, and two cross bars 15 are fixedly provided between the two legs 13, and the ends of the cross bars 15 pass through the through holes 14 of the legs 13, and the upper ends of the legs 13 are in sliding contact with the bucket 1. Therefore, after adjusting the spacing between the two running wheels 12, the positions of the legs 13 can be adjusted to prevent the legs 13 from contacting the jagged roadside of the road and affecting the movement of the bucket 1. In the actual improvement process, one of the cross bars 15 can be adjusted to a bidirectional screw, and the relative positions of the two legs 13 can be adjusted by rotating the bidirectional screw. At the same time, the positions of the two legs 13 can be limited by the action of the bidirectional screw, so that they are stably placed relative to the bucket 1.

[0029] like Figure 4 As shown, in order to adjust the position of the supporting mechanism 2, the adjusting and fixing mechanism 3 includes a bidirectional screw 33, two fixing plates 34 and two diagonal support plates 31. The two fixing plates 34 are symmetrically arranged and do not contact each other. At the same time, a snap groove 35 is arranged on the two fixing plates 34. The bidirectional screw 33 penetrates the two fixing plates 34. A snap slide 32 is arranged at the snap groove 35. The bidirectional screw 33 threadably penetrates the snap slide 32. The lower end of the snap slide 32 is hingedly provided with a diagonal support plate 31. The lower end of the diagonal support plate 31 is hingedly provided with a connecting pipe 24. The two connecting pipes 24 are respectively sleeved on the two ends of the supporting mechanism 2. When it is necessary to adjust the spacing of the traveling wheels 12, the staff can rotate the bidirectional screw 33 to force the snap slide 32 to move in the snap slide groove 35, adjust the inclination angle of the diagonal support plate 31, and force the support mechanism 2 to rise and fall relative to the bucket cart 1. At the same time, support is provided for the traveling wheels 12 to move to the bottom of the bucket cart 1 (that is, the uppermost end of the traveling wheels 12 is lower than the bottom surface of the bucket cart 1), thereby facilitating the adjustment of the spacing between the two traveling wheels 12.

[0030] like Figure 5 , Figure 7As shown, in order to adjust the spacing between the two running wheels 12, the support mechanism 2 includes an intermediate shaft 21 and two secondary shafts 22. Both ends of the intermediate shaft 21 are set to be open, and a rotating shaft 29 is set inside. A plurality of friction columns 25 are set on the intermediate shaft 21. The plurality of friction columns 25 are located in the middle of the intermediate shaft 21 and are evenly distributed along the circumferential direction of the intermediate shaft 21. Two sets of threads are symmetrically set at both ends of the rotating shaft 29. The ends of the two secondary shafts 22 close to each other are inserted into the intermediate shaft 21. The rotating shaft 29 is threadedly inserted into the thread groove 23 of the secondary shaft 22. The two connecting pipes 24 are respectively fixedly sleeved on the two secondary shafts 22. When the running wheels 12 are located below the bucket car 1, the staff can rotate the intermediate shaft 21 to drive the rotating shaft 29 to rotate synchronously with the intermediate shaft 21, thereby controlling the two secondary shafts 22 to approach each other. In this process, the inclination angle of the diagonal support plate 31 changes again until the spacing between the two running wheels 12 meets the road requirements. After adjusting the distance between the two running wheels 12, the staff can also rotate the bidirectional screw 33 to adjust the distance between the running wheels 12 and the bucket 1 again, so as to put the device in a stable working state. The setting of the friction column 25 is convenient for increasing the resistance of the staff holding the intermediate shaft 21.

[0031] like Figure 6 As shown, in order to prevent the intermediate shaft 21 from rotating relative to the secondary shaft 22 during the operation of the device, multiple extrusion plates 28 are arranged at both ends of the intermediate shaft 21. The multiple extrusion plates 28 are evenly distributed along the circumferential direction of the intermediate shaft 21, and the outer side of the extrusion plates 28 is set as a slope, that is, the size of the extrusion plate 28 away from the intermediate shaft 21 is larger than the size of the end close to the intermediate shaft 21. Both ends of the intermediate shaft 21 are provided with a threaded groove 26, and the threaded sleeve of the threaded groove 26 is provided with an internal threaded tube 27. One end of the internal threaded tube 27 can press the multiple extrusion plates 28 together to fit the secondary shaft 22. Under the extrusion of the extrusion plates 28, the resistance to the relative rotation of the intermediate shaft 21 and the secondary shaft 22 is increased, so that they remain relatively stationary. The setting of the internal threaded tube 27 can be moved relative to the intermediate shaft 21 as needed, which provides convenience for adjusting the relative position of the intermediate shaft 21 and the secondary shaft 22. Example 2

[0032] like Figure 1 , Figure 2 , Figure 3As shown, a construction material transport trolley for non-standard road sections includes a bucket 1, a support mechanism 2 and an adjustment and fixing mechanism 3. The support mechanism 2 and the adjustment and fixing mechanism 3 are both arranged below the bucket 1. The support mechanism 2 is arranged below the adjustment and fixing mechanism 3, and the position of the support mechanism 2 relative to the bucket 1 can be adjusted by changing the state of the adjustment and fixing mechanism 3. Travel wheels 12 are arranged on both sides of the bucket 1. The two travel wheels 12 are respectively sleeved on the two ends of the support mechanism 2, and the support mechanism 2 can change its own length according to demand, so that the travel wheels 12 are located directly below the bucket 1, and the distance between the two travel wheels 12 is reduced, so that it can adapt to narrower roads, provide convenience for workers to move construction materials, and reduce labor intensity. Two legs 13 are provided at the lower end of the bucket 1, and two cross bars 15 are fixedly provided between the two legs 13, and the ends of the cross bars 15 pass through the through holes 14 of the legs 13, and the upper ends of the legs 13 are in sliding contact with the bucket 1. Therefore, after adjusting the spacing between the two running wheels 12, the positions of the legs 13 can be adjusted to prevent the legs 13 from contacting the jagged roadside of the road and affecting the movement of the bucket 1. In the actual improvement process, one of the cross bars 15 can be adjusted to a bidirectional screw, and the relative positions of the two legs 13 can be adjusted by rotating the bidirectional screw. At the same time, the positions of the two legs 13 can be limited by the action of the bidirectional screw, so that they are stably placed relative to the bucket 1.

[0033] like Figure 4 As shown, in order to adjust the position of the supporting mechanism 2, the adjusting and fixing mechanism 3 includes a bidirectional screw 33, two fixing plates 34 and two diagonal support plates 31. The two fixing plates 34 are symmetrically arranged and do not contact each other. At the same time, a snap groove 35 is arranged on the two fixing plates 34. The bidirectional screw 33 penetrates the two fixing plates 34. A snap slide 32 is arranged at the snap groove 35. The bidirectional screw 33 threadably penetrates the snap slide 32. The lower end of the snap slide 32 is hingedly provided with a diagonal support plate 31. The lower end of the diagonal support plate 31 is hingedly provided with a connecting pipe 24. The two connecting pipes 24 are respectively sleeved on the two ends of the supporting mechanism 2. When it is necessary to adjust the spacing of the traveling wheels 12, the staff can rotate the bidirectional screw 33 to force the snap slide 32 to move in the snap slide groove 35, adjust the inclination angle of the diagonal support plate 31, and force the support mechanism 2 to rise and fall relative to the bucket cart 1. At the same time, support is provided for the traveling wheels 12 to move to the bottom of the bucket cart 1 (that is, the uppermost end of the traveling wheels 12 is lower than the bottom surface of the bucket cart 1), thereby facilitating the adjustment of the spacing between the two traveling wheels 12.

[0034] like Figure 5 , Figure 7As shown, in order to adjust the spacing between the two running wheels 12, the support mechanism 2 includes an intermediate shaft 21 and two secondary shafts 22. Both ends of the intermediate shaft 21 are set to be open, and a rotating shaft 29 is set inside. A plurality of friction columns 25 are set on the intermediate shaft 21. The plurality of friction columns 25 are located in the middle of the intermediate shaft 21 and are evenly distributed along the circumferential direction of the intermediate shaft 21. Two sets of threads are symmetrically set at both ends of the rotating shaft 29. The ends of the two secondary shafts 22 close to each other are inserted into the intermediate shaft 21. The rotating shaft 29 is threadedly inserted into the thread groove 23 of the secondary shaft 22. The two connecting pipes 24 are respectively fixedly sleeved on the two secondary shafts 22. When the running wheels 12 are located below the bucket car 1, the staff can rotate the intermediate shaft 21 to drive the rotating shaft 29 to rotate synchronously with the intermediate shaft 21, thereby controlling the two secondary shafts 22 to approach each other. In this process, the inclination angle of the diagonal support plate 31 changes again until the spacing between the two running wheels 12 meets the road requirements. After adjusting the distance between the two running wheels 12, the staff can also rotate the bidirectional screw 33 to adjust the distance between the running wheels 12 and the bucket 1 again, so as to put the device in a stable working state. The setting of the friction column 25 is convenient for increasing the resistance of the staff holding the intermediate shaft 21.

[0035] like Figure 6 As shown, in order to prevent the intermediate shaft 21 from rotating relative to the secondary shaft 22 during the operation of the device, multiple extrusion plates 28 are arranged at both ends of the intermediate shaft 21. The multiple extrusion plates 28 are evenly distributed along the circumferential direction of the intermediate shaft 21, and the outer side of the extrusion plates 28 is set as a slope, that is, the size of the extrusion plate 28 away from the intermediate shaft 21 is larger than the size of the end close to the intermediate shaft 21. Both ends of the intermediate shaft 21 are provided with a threaded groove 26, and the threaded sleeve of the threaded groove 26 is provided with an internal threaded tube 27. One end of the internal threaded tube 27 can press the multiple extrusion plates 28 together to fit the secondary shaft 22. Under the extrusion of the extrusion plates 28, the resistance to the relative rotation of the intermediate shaft 21 and the secondary shaft 22 is increased, so that they remain relatively stationary. The setting of the internal threaded tube 27 can be moved relative to the intermediate shaft 21 as needed, which provides convenience for adjusting the relative position of the intermediate shaft 21 and the secondary shaft 22.

[0036] like Figure 1 , Figure 4 As shown, in order to facilitate the staff to rotate the bidirectional screw 33, the fixed plate 34 is fixedly connected to the bucket car 1, a pulley is provided in the middle of the bidirectional screw 33, and a driving wheel is provided at the end below the bucket car 1. The driving wheel and the pulley are connected by a transmission belt 11. The staff can directly control the rotation of the driving wheel on the side of the bucket car 1 to realize the rotation of the bidirectional screw 33, avoiding the situation where the bottom space is narrow before the bucket car 1 is adjusted and it is inconvenient for the staff to crawl under the bucket car 1 to complete the adjustment.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
