Description

Technical Field

[0001] This invention belongs to the field of highway slope construction technology and relates to a material conveying device for highway slope construction. Background Technology

[0002] Highway slopes refer to the sloping surfaces on both sides of the roadbed that connect to the ground. They are divided into embankment slopes and cutting slopes, and are an important factor affecting the stability of the roadbed. In order to prevent rocks from rolling down highway slopes, it is necessary to cover the highway slopes with protective nets. However, when covering the slopes with protective nets, multiple net installers need to work together to lay the woven protective nets from top to bottom, use the weight of the nets themselves to hang them down, unfold the nets, and finally stretch and fix them to achieve the protective function.

[0003] Existing protective netting material conveying equipment involves suspending the protective netting at the required laying location, then having multiple workers unload it from the equipment before laying it. However, this process presents several problems: 1. During laying, the protective netting rubs against the slope, loosening fallen rocks and creating a safety hazard for the material conveying equipment below the slope; 2. The overall operation of laying the protective netting is complex, requiring fixing, stretching, and re-fixing. Each step requires independent operation by the workers, and the material conveying equipment cannot cooperate, slowing down highway slope construction. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this invention proposes a material conveying device for highway slope construction, which is achieved through the following technical solution:

[0005] A material conveying device for highway slope construction includes a telescopic lifting device, a connecting frame, a telescopic sleeve, and an adjusting component. The telescopic lifting device includes multiple telescopic arms; the two farthest arms are controlled separately from the other arms; the connecting frame is connected to the farthest arms; the adjusting component is located within the connecting frame; a telescopic sleeve is provided between the adjusting components; the telescopic sleeve is extended and retracted through the adjusting components; resistance adjusting components are connected to both ends of the telescopic sleeve, and these components are connected to the two farthest arms to adjust the rotational speed of the telescopic sleeve; a protective net is wound around the telescopic sleeve; the protective net is laid from the bottom of the slope upwards by the lifting of the telescopic arms; as the protective net is stretched, gravity and elasticity increase, activating the two farthest arms to activate the resistance adjusting components and reduce the rotational speed of the telescopic sleeve.

[0006] Furthermore, the adjustment assembly includes gears, gears are rotatably connected to the inner wall of the connecting frame, and adjusting rods are symmetrically slidably connected to the inner wall of the connecting frame. A rack is fixedly connected to one side of the two adjusting rods that are close to each other, and both racks are meshed with the gears. An electric push rod is fixedly connected to one side of the connecting frame, and the output end of the electric push rod is fixedly connected to one of the adjusting rods. A telescopic sleeve is rotatably connected between the two adjusting rods. The electric push rod provides telescopic power, which, in conjunction with the gears and racks, causes the two adjusting rods to telescopically extend and retract, and drives the telescopic sleeve to telescopically extend and retract.

[0007] Furthermore, the resistance adjustment assembly includes clearance grooves at the ends of the two adjustment rods. A square column is fixedly connected to the inner wall of the clearance groove, and a blocking ring is fixedly connected to the end of the square column away from the clearance groove. An adjustment ring is sleeved on the outer wall of the end of the square column located in the clearance groove. A connecting plate is slidably connected to the outer wall of the end of the square column near the blocking ring. An active resistance tooth is fixedly connected to the end of the connecting plate near the telescopic sleeve. An adjustment spring is provided between the connecting plate and the adjustment ring, and the adjustment spring is sleeved on the outer wall of the square column. Driven resistance teeth are symmetrically fixedly connected to both ends of the telescopic sleeve. The active resistance teeth and driven resistance teeth are meshed. A lever is fixedly connected to one side of the adjustment ring, and the lever extends out of the adjustment rod. A mounting base is fixedly connected to the ends of the two adjustment rods. A trapezoidal block is slidably connected inside the mounting base. The inclined end of the trapezoidal block is tangent to the lever. Pull ropes are fixedly connected to one side of each of the two trapezoidal blocks. The two pull ropes are fixedly connected to the second-to-last section of the farthest end of the telescopic arm.

[0008] Furthermore, the mounting base has symmetrically opened sliding grooves inside, and ear plates are symmetrically fixedly connected to both sides of the trapezoidal block. The ear plates are slidably connected to the sliding grooves, and a return spring is fixedly connected to one side of the ear plate. One end of the return spring is fixedly connected to the inner wall of the sliding groove.

[0009] Furthermore, one of the mounting bases is fixedly connected to a motor, and the output end of the motor extends out a square post and a blocking ring, which are fixedly connected to the telescopic sleeve.

[0010] Furthermore, the end of the active resistance tooth that contacts the driven resistance tooth has a rounded corner.

[0011] Furthermore, the telescopic sleeve has symmetrical first grooves at both ends, and driven resistance teeth are arranged on the outer periphery of the first grooves.

[0012] Furthermore, the telescopic sleeve is provided with equidistant placement slots, and a stop bar is rotatably connected to the inner wall of the placement slot. The placement slot has a notch in the middle of the stop bar, and the other end of the stop bar is fixedly connected to the inside of the placement slot by bolts.

[0013] The beneficial effects of this invention compared to the prior art are as follows:

[0014] This invention uses a bottom-up installation method to fix the lower part of the protective netting to the bottom of the slope. By activating the telescopic arm (without activating the two furthest sections of the telescopic arm), the upper part of the protective netting is transported to the installation point on the slope. Through the extension of the telescopic arm, the telescopic sleeve rotates in conjunction with the protective netting, counteracting the elasticity of the protective netting itself and the force of gravity. Through a series of actions, the protective netting is stretched and laid out. The laying device described in this invention effectively avoids the risk of falling rocks when laying protective netting on slopes. The bottom-up transportation and laying method of the protective netting effectively speeds up the slope construction progress. Attached Figure Description

A slope 2 is located beside a highway 1, with mounting nails 5 on the slope 2. A crane 3 is located on the highway 1, and a telescopic boom 4 is mounted on the crane 3. The two farthest telescopic sections of the telescopic boom 4 are controlled separately from the other telescopic sections. A connecting frame 6 is located at the end of the telescopic boom 4, and an adjustment component is located inside the connecting frame 6. A telescopic sleeve 7 is located between the adjustment components, and a resistance adjustment component is located inside the adjustment components. The resistance adjustment component is installed in conjunction with both ends of the telescopic sleeve 7. The telescopic sleeve 7 has symmetrically formed first grooves 29 at both ends.

[0025] Please see Figure 1-7 As shown, the adjustment assembly includes a gear 8, a gear 8 rotatably connected to the inner wall of the connecting frame 6, and adjusting rods 9 symmetrically slidably connected to the inner wall of the connecting frame 6. A rack 10 is fixedly connected to one side of the two adjusting rods 9 that are close to each other. Both racks 10 are meshed with the gear 8. An electric push rod 11 is fixedly connected to one side of the connecting frame 6. The output end of the electric push rod 11 is fixedly connected to one of the adjusting rods 9. A telescopic sleeve 7 is rotatably connected between the ends of the two adjusting rods 9. The electric push rod 11 provides telescopic power, which, in conjunction with the gear 8 and the rack 10, causes the two adjusting rods 9 to telescopically extend and retract, and drives the telescopic sleeve 7 to telescopically extend and retract.

[0026] Please see Figure 1-7 As shown, the resistance adjustment assembly includes a clearance groove 12. Both ends of the two adjustment rods 9 are provided with clearance grooves 12. A square column 13 is fixedly connected to the inner wall of the clearance groove 12. A blocking ring 14 is fixedly connected to the end of the square column 13 away from the clearance groove 12. An adjustment ring 15 is sleeved on the outer wall of the end of the square column 13 located in the clearance groove 12. A connecting plate 16 is slidably connected to the outer wall of the end of the square column 13 near the blocking ring 14. An active resistance tooth 17 is fixedly connected to the end of the connecting plate 16 near the telescopic sleeve 7. An adjustment spring 18 is provided between the connecting plate 16 and the adjustment ring 15. The adjustment spring 18 is sleeved on the outer wall of the square column 13. The two ends of the telescopic sleeve 7 are symmetrically fixedly connected to driven resistance teeth 19 around the first groove 29. The active resistance tooth 17 and the driven resistance tooth 19 are meshed and connected. The ends of the active resistance tooth 17 and the driven resistance tooth 19 that are in contact with each other are provided with rounded corners.

[0027] A lever 20 is fixedly connected to one side of the adjusting ring 15, and the lever 20 extends out of the adjusting rod 9. Mounting seats 21 are fixedly connected to the ends of the two adjusting rods 9. Trapezoidal blocks 22 are slidably connected inside the mounting seats 21. The inclined end of the trapezoidal blocks 22 is tangent to the lever 20. Pull ropes 23 are fixedly connected to one side of each of the two trapezoidal blocks 22. The two pull ropes 23 are fixedly connected to the second-to-last section of the telescopic arm 4 at its farthest end. Sliding grooves 24 are symmetrically provided inside the mounting seats 21. Ear plates 25 are symmetrically fixedly connected to both sides of the trapezoidal blocks 22. The ear plates 25 are slidably connected to the sliding grooves 24, and a return spring 30 is fixedly connected to one side of the ear plates 25. One end of the return spring 30 is fixedly connected to the inner wall of the sliding groove 24. A motor 26 is fixedly connected to one of the mounting seats 21. The output end of the motor 26 extends out of the square post 13 and the blocking ring 14, and extends into the first groove 29 to be fixedly connected to the telescopic sleeve 7. Placement grooves 27 are equidistantly provided on the telescopic sleeve 7. The inner wall of the placement grooves 27 is rotatably connected. There is a stop bar 28, and a placement groove 27 is located in the middle of the stop bar 28 with a notch. The other end of the stop bar 28 is fixedly connected to the inside of the placement groove 27 by bolts. Through the extension of the telescopic arm 4, the telescopic sleeve 7 is rotated in conjunction with the protective net. The rotation of the telescopic sleeve 7 causes friction and misalignment between the active resistance tooth 17 and the driven resistance tooth 19. The elastic force provided by the adjusting spring 18 is used to counteract the elastic force of the protective net itself and the downward gravity, so that the protective net always maintains a certain tension when stretched. As the protective net is stretched continuously, the gravity and elastic force increase. At this time, the two telescopic sections at the farthest end of the telescopic arm 4 are started. The trapezoidal block 22 is moved by the two pull ropes 23, so that its inclined surface presses against the deflector 20. The deflector 20 drives the adjusting ring 15 to move. Under the action of the elastic force of the adjusting spring 18, the connecting plate 16 increases the force required to form friction and misalignment between the active resistance tooth 17 and the driven resistance tooth 19, thereby preventing the telescopic sleeve 7 from rotating too fast.

[0028] Working principle:

[0029] In use, the crane 3 is first moved to the bottom of the slope 2, and the electric push rod 11 is started, which drives one of the adjusting rods 9 to move. Through the cooperation of the two racks 10 and the gear 8, the two adjusting rods 9 move relative to each other, causing the telescopic sleeve 7 to be compressed. Then, the telescopic arm 4 is started to lower the connecting frame 6 to near the ground. Then, the bolts on the stop rod 28 are removed. After removal, the edge of the rolled woven protective net is fitted with the stop rod 28. Then, the stop rod 28 is fixed in the placement groove 27, with the edge of the protective net located in the placement groove 27. At this time, the motor 26 is started, which drives the telescopic sleeve 7 to rotate. The telescopic sleeve 7 wraps the protective net around its outer wall. One end of the protective net is fixed to the mounting nail 5. Then, the telescopic arm 4 is started (the two farthest sections of the telescopic arm 4 are not started) to transport the other end of the protective net to the installation point (shaped) on the slope 2. (In a bottom-up installation method), the extension of the telescopic arm 4, in conjunction with the protective net, causes the telescopic sleeve 7 to rotate. The rotation of the telescopic sleeve 7 causes friction and misalignment between the active resistance tooth 17 and the driven resistance tooth 19. The elastic force provided by the adjusting spring 18 is used to counteract the elastic force of the protective net itself and the downward gravity, so that the protective net always maintains a certain tension when stretched. As the protective net is stretched continuously, the gravity and elastic force increase. At this time, the two sections at the farthest end of the telescopic arm 4 are started. The trapezoidal block 22 is moved by the two pull ropes 23, so that its inclined surface presses against the deflector 20. The deflector 20 drives the adjusting ring 15 to move. Under the action of the elastic force of the adjusting spring 18, the connecting plate 16 increases the force required to form friction and misalignment between the active resistance tooth 17 and the driven resistance tooth 19, thereby preventing the telescopic sleeve 7 from rotating too fast.

[0030] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all of these should be considered to fall within the scope of patent protection determined by the submitted claims.
