[0033] like Figure 1 to Figure 6 As shown, the present invention is a material and slag transfer system for pile foundation construction in mountainous areas, including rails 1 arranged side by side, a plurality of transfer vehicles are arranged on the rails 1, and the transfer vehicles include a frame 2, and the frame 2 is provided with a driving structure, and the driving structure is used to drive the frame 2 to move on the rail 1, and a mounting plate 16 is provided above the frame 2, and the mounting plate 16 is fixedly connected to the frame 2, and a bearing plate 3 is provided above the mounting plate 16, and side baffles 4 are provided on both ends of the bearing plate 3 arranged perpendicular to the length direction of the rail 1, and one end of the side baffle 4 is fixed on the bearing plate 3, and the two side baffles 4 are arranged opposite to each other. Vertically distributed limiting grooves 5 are provided on both edges of the surface, and the limiting grooves 5 are connected to one side of the two side baffles 4 facing the middle of the bearing plate 3. Screws 6 are provided in the limiting grooves 5, one end of the screw 6 is fixed to the bearing plate 3, and a locking nut 7 is provided on the other end of the screw 6. A plurality of baffles 11 are provided in the two limiting grooves 5 arranged opposite to each other of the two side baffles 4, and a first through hole 13 is penetrated at both ends of the baffle 11, and the first through hole 13 is sleeved on the screw 6, and a plurality of baffles 11 are stacked, and the locking nut 7 presses the plurality of baffles 11 tightly into the limiting grooves 5.

[0034] The working principle of this technical solution is:

[0035] The track 1 is erected on the mountain from the foot of the mountain to the construction site, and its erection path should pass through several construction sites. Therefore, when transporting small materials or slag, it is only necessary to lift the materials into the space formed by the side baffles 4 and the baffle bars 11, and then drive the transfer vehicle to travel on the track 1 through the driving device, so that the materials or slag can be transported to the designated location. It is not difficult to understand that the advantage of installing several baffle bars 11 on the side panels of the row layer is that the baffle bars 11 can be removed at any time, which is convenient for the transportation of longer materials and for loading and unloading. At the same time, the setting of the screw rod 6 can not only limit the deflection of the baffle bar 11, but also fix the position of the baffle bar 11 by cooperating with the locking nut 7. That is, the technical solution provides greater convenience for the transportation of materials or slag during construction in mountainous areas, simplifies the material transportation process, and improves construction efficiency.

[0036] In one feasible embodiment, a plurality of position-matched clamping arc holes 12 are provided on the contact surfaces of adjacent baffles 11, and the clamping arc holes 12 are evenly distributed along the length direction of the baffles 11. A turntable 10 is provided in the middle of the mounting plate 16, and the middle of the supporting plate 3 is fixed on the turntable 10. Position-matched limit holes 8 are provided on the mounting plate 16 and the supporting plate 3, and limit pins 9 are provided in the limit holes 8.

[0037] The advantage of providing the clamping arc hole 12 is that the end of the steel bar 15 can be clamped in the space formed by the clamping arc hole 12 of the adjacent retaining bar 11, that is, with the effect of the locking nut 7, the clamping arc hole 12 can be squeezed and pressed against the steel bar 15, that is, at this time, only two adjacent transfer vehicles need to be used in coordination to clamp the ends of the steel bar 15, thereby achieving the limit and fixation of the steel bar 15;

[0038] At the same time, it is not difficult to understand that the layout path of the track 1 cannot be completely straight. Therefore, in the curved part of the track 1, since the steel bars 15 are long, in order to prevent the steel bars 15 from falling off due to the inclination or shaking of the track 1 during transportation, the two ends of the steel bars 15 should be firmly fixed on the transfer vehicle. This will cause the transfer vehicle to be turned. Due to the long distance between the two adjacent transfer vehicles, the steel bars 15 will be subjected to a torsional moment, which will cause the movement of the two transfer vehicles to be stuck by the steel bars 15. Therefore, in this technical solution, a turntable 10 (existing technology, which can also be understood as a rotating shaft or bearing) is provided to enable the bearing plates 3 on the front and rear transfer vehicles to rotate relative to the mounting plate 16. Therefore, when the steel bars 15 are subjected to a torsional moment, the two ends of the steel bars 15 will respectively drive the bearing plates 3 to rotate, thereby unloading the torsional moment, and thus will not affect the movement of the two transfer vehicles;

[0039] Furthermore, the setting of the limit hole 8 and the limit pin 9 can control whether the bearing plate 3 rotates, that is, when transporting steel bars 15, the limit pin 9 is cancelled, and when transporting small materials, the limit pin 9 is inserted to ensure the stability of small materials during transportation.

[0040] In one feasible manner, one end of the limit pin 9 is arranged to pass through the mounting plate 16, and the limit pin 9 is detachably connected to the mounting plate 16. A thread is provided on the inner wall of the limit hole 8 arranged on the mounting plate 16, and the limit pin 9 is threadedly connected to the mounting plate 16. This arrangement makes it easy for construction personnel to operate the position of the limit pin 9.

[0041] In one practicable manner, the driving structure includes a gasoline engine and a clamping roller, the clamping roller is connected to the mounting plate 16, and the clamping roller is clamped on the track 1, and the gasoline engine is used to drive the clamping roller to rotate. Part of the driving structure can be understood as the prior art, and specific reference can be made to the design method of the single-track or double-track transport vehicle in the prior art.

[0042] In one feasible manner, the cross-section of the baffle bar 11 is square, and a second through hole 14 is further provided on the end of the baffle bar 11, and the second through hole 14 and the first through hole 13 are arranged to be vertically connected. The purpose of the square cross-section of the baffle bar 11 is that no matter how the baffle bar 11 rotates, it can be placed in the limit groove 5. At the same time, the advantage of the setting of the second through hole 14 is that when transporting powdered materials (cement, sand and gravel), the second through hole 14 can be sleeved on the screw 6 to stagger the clamping arc holes 12 set on two adjacent baffle bars 11, and the clamping arc holes 12 are arranged in an upper and lower position at this time. The advantage of this is that the contact between adjacent baffle bars 11 can achieve close contact (which can be understood as no gaps or voids), thereby ensuring that when transporting materials or slag, small individuals will not leak out from between adjacent baffle bars 11, thereby improving the environmental protection and safety of construction.

[0043] In one feasible method, a rubber anti-skid layer is provided on the inner wall of the clamping arc hole 12, and the rubber anti-skid layer is bonded inside the clamping arc hole 12, which can enhance the friction force on the contact part of the steel bar 15, ensure the limiting effect on the steel bar 15, and avoid slipping out at the inclined track 1.

[0044] In one feasible method, the laying path of the track 1 passes through the slag accumulation area of ​​the pile foundation construction, and a lifting device is provided in the slag accumulation area. The lifting device is existing technology, for example, it is composed of a mounting frame and a hand winch, and the mounting frame can rotate, that is, the track 1 can be set within its rotation radius, which can improve the loading and unloading efficiency of materials or slag.

[0045] A method for transferring materials and slag for pile foundation construction in mountainous areas, comprising the following steps:

[0046] S1. Confirm the type of the transferred article and adaptively install the barrier bar 11 according to the type of the transferred article;

[0047] S2. When the transported items are slag or small-volume materials, the second through hole 14 of the baffle 11 is sleeved on the screw 6, and the clamping arc holes 12 provided on the baffle 11 are arranged in an upper and lower distribution, that is, at this time, the contact surfaces of adjacent baffles 11 are sealed;

[0048] S21, then the slag is moved to the space surrounded by the baffle 11 and the side baffle 4 by manual labor or lifting equipment, and then the frame is driven by the driving structure to move on the track 1, thereby transporting and transferring the slag;

[0049] S3. When the transported object is a steel bar 15, the first through hole 13 of the blocking bar 11 is sleeved on the screw rod 6, and the clamping arc holes 12 provided on adjacent blocking bars 11 are arranged opposite to each other;

[0050] S31, move the positions of the two adjacent transfer vehicles to match the length of the steel bar 15, and then place the two ends of the steel bar 15 in the clamping arc holes 12 arranged opposite to each other on the two transfer vehicles. After the placement is completed, rotate the locking nut 7 to lock the position of the blocking bar 11;

[0051] S32, then pull out the limit pin 9, and then drive the frame to move on the track 1 through the driving structure, and then transport and transfer the steel bars 15.

[0052] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
