DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the roadbed reinforcement construction equipment provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the second viewing angle structure; Figure 3 for Figure 1 Schematic diagram of the structure of the upward viewing angle; Figure 4 for Figure 3 An enlarged schematic diagram of part A is shown; Figure 5 It is a schematic diagram of the connection structure of a pair of adjusting rods, connecting rods and other components; Figure 6 for Figure 5 Schematic diagram of the structure from a bird's-eye view; Figure 7 for Figure 6 An enlarged schematic diagram of part B is shown; Figure 8 for Figure 6 An enlarged schematic diagram of part C is shown; Fig. 9 for Figure 6 An enlarged schematic diagram of part D is shown. The roadbed reinforcement construction equipment includes: a support plate 1 for carrying filler materials and tools that may be required for reinforcement construction; two pairs of axle seats are fixedly connected to the bottom of the support plate 1 to support axles 3; one axle 3 passes through a pair of axle seats and the other axle 3 passes through another pair of axle seats. A pair of axles 3 can rotate freely around their own axis; each axle 3 is rotatably connected to a roller 4 at each end, and the roller 4 touches the ground to support and facilitate the movement of the entire reinforcement construction equipment. The above are all prior arts and will not be described in detail here.

[0030] It also includes a ratchet 5, a mounting seat 2, a guide sleeve 6, an obstruction reversal block 7 used in conjunction with the ratchet 5, an adjustment rod 8 for adjusting the position of the obstruction reversal block 7 relative to the ratchet 5, a first limit block 9 and a second limit block 10.

[0031] A ratchet 5 is coaxially fixedly connected to the wheel axle 3; a mounting seat 2 and a guide sleeve 6 are fixedly connected to the lower part of the supporting plate 1, an adjusting rod 8 slides through the mounting seat 2 and the guide sleeve 6 is slidably sleeved on the adjusting rod 8, and the mounting seat 2 and the guide sleeve 6 can both support and guide the adjusting rod 8; the adjusting rod 8 slides through the mounting seat 2, and under the guidance of the mounting seat 2 and the guide sleeve 6, the adjusting rod 8 can slide freely along its own axis; a first limit block 9, a second limit block 10 and a reversal blocking block 7 are fixedly connected to the adjusting rod 8, and the first limit block 9 is positioned at the bottom of the adjusting rod 8. On the outside of the mounting seat 2, the second limit block 10 and the reversal blocking block 7 are located on the inside of the mounting seat 2. When the adjusting rod 8 slides to the point where the first limit block 9 abuts against the outer side of the mounting seat 2, the reversal blocking block 7 abuts against the ratchet 5. At this time, the wheel can only rotate in one direction in the forward direction, that is, the device cannot move backward by rotating the tire; when the adjusting rod 8 slides to the point where the second limit block 10 abuts against the inner side of the mounting seat 2, the reversal blocking block 7 completely leaves the ratchet 5. At this time, the wheel can rotate in both directions, that is, the device can move freely forward and backward by rotating the tire.

[0032] Furthermore, it also includes a connecting rod 11, one end of which is fixedly connected to an adjustment rod 8, and the other end of the connecting rod 11 is fixedly connected to another adjustment rod 8. When sliding the adjustment rod 8, the force point is on the connecting rod 11, and the two adjustment rods 8 can be slid out synchronously at one time, without sliding the adjustment rods 8 one by one, saving operation steps and making it more convenient to use. A rubber sleeve 12 is fixedly sleeved on the connecting rod 11 to protect the palm skin and increase the comfort of hand holding; the surface of the rubber sleeve is provided with anti-slip grooves 13 to increase the friction of hand holding and reduce the possibility of injury to the operator due to hand slippage.

[0033] As another implementation of this embodiment, it also includes a screw 14; a mounting seat 2 is fixedly connected to the lower side of the support plate 1, and the screw 14 rotates through the mounting seat 2, and the mounting seat 2 is used to support and guide the screw 14, so that the screw 14 can rotate around its own axis;

[0034] The connecting rod 11 is fixedly connected with a threaded sleeve 15, and the thread of the connecting rod 11 passes through the threaded sleeve 15. The movement of the threaded sleeve 15 relative to the connecting rod 11 can drive the adjusting rod 8 to slide. At the same time, the thread locking force between the threaded sleeve 15 and the connecting rod 11 can keep the adjusting rod 8 in the adjusted position.

[0035] A first stopper 16, a second stopper 17 and a rotating handle 18 are fixedly connected to the screw rod 14. The first stopper 16 abuts against the outer side surface of the mounting seat 2, and the second stopper 17 abuts against the inner side surface of the mounting seat 2. The first stopper 16 and the second stopper 17 work together to prevent the screw rod 14 from moving along its own axial direction. The screw rod 14 is rotated by holding the rotating handle 18. Due to the connection between the screw rod 14 and the threaded sleeve 15 and the limiting effect of the connecting rod 11, the threaded sleeve 15 will move along the axial direction of the screw rod 14, thereby realizing the sliding of the adjusting rod 8. When the adjusting rod 8 slides out to the target position, the locking force of the screw rod 14 and the threaded sleeve 15 can keep the adjusting rod 8 at the target position unchanged.

[0036] Furthermore, the rotating handle 18 includes a fixing portion 1801 and an adjusting portion 1802. The fixing portion 1801 is provided with a threaded adjusting groove 1803. The outer surface of the adjusting portion 1802 is provided with an external thread. The threaded sleeve 15 of the fixing portion 1801 is connected to the adjusting portion 1802. By rotating the adjusting portion 1802, the overlapping length of the adjusting portion 1802 and the fixing portion 1801 can be adjusted, thereby adjusting the torque length of the rotating handle 18 to adapt to operators with different strengths.

[0037] Furthermore, the fixing part 1801 is provided with a limiting groove 1804 connected with the threaded adjustment groove 1803, and the limiting groove 1804 is located inside the threaded adjustment groove 1803; the adjusting part 1802 is fixedly connected with a third limiting block 1805 matching the limiting groove 1804, and the third limiting block 1805 is located inside the limiting groove 1804. When the adjusting part 1802 is rotated outward to the maximum extent, the limiting block abuts against the connection between the limiting groove 1804 and the threaded adjustment groove 1803. By providing the third limiting block 1805 and the limiting groove 1804, the maximum extent to which the adjusting part 1802 is allowed to rotate outward can be limited, so as to avoid the adjusting part 1802 and the fixing part 1801 overlapping too little, resulting in the adjusting part 1802 being separated from the fixing part 1801 during the rotation process and causing injuries.

[0038] Furthermore, a ball groove 19 is opened on the outer surface of the adjusting rod 8, and a ball 20 is rollingly connected in the ball groove 19. The ball 20 is in contact with the inner surface of the guide sleeve 6. By providing the ball 20, the sliding resistance between the adjusting rod 8 and the guide sleeve 6 when sliding along the guide sleeve 6 can be reduced, and the operation is more labor-saving.

[0039] Furthermore, the mounting seat 2 is embedded with a bearing 21, and the bearing 21 is fixedly sleeved on the screw 14, so the rotation resistance of the screw 14 around its own axis is reduced; when the screw 14 rotates around its own axis, there is sliding resistance between the first stopper 16 and the outer side of the mounting seat 2, and there is also sliding resistance between the second stopper 17 and the inner side of the mounting seat 2, so the first stopper 16 is rollingly connected to the side of the mounting seat 2 and the second stopper 17 is rollingly connected to the side of the mounting seat 2, which is conducive to reducing the above two sliding frictions. The inner and outer sides of the mounting seat 2 are both provided with an annular limiting groove 22, and the ball 20 moves in a circle along the annular limiting groove 22, so the annular limiting groove 22 has a guiding and limiting effect on the rotation of the screw 14.

[0040] The working principle of the roadbed reinforcement construction equipment provided by the utility model is as follows:

[0041] When the construction equipment moves onto the slope, hold the adjusting rod 8 and slide it inward until the first limit block 9 abuts against the outer side of the mounting seat 2. At this time, the reversal block 7 and the ratchet 5 are abutted against each other, and the wheel axle 3 can only rotate in the forward direction but cannot rotate in the backward direction; therefore, the equipment can be prevented from moving backward on the slope by rolling the roller 4.

[0042] After the reinforcement operation is completed, the adjusting rod 8 slides to the second limit block 10 against the inner side of the mounting seat 2. At this time, the blocking reversal block 7 completely leaves the ratchet 5. At this time, the wheel can rotate along the forward movement direction and the backward movement direction. At this time, the reinforcement construction equipment can be moved freely.

[0043] Compared with the related art, the roadbed reinforcement construction equipment provided by the utility model has the following beneficial effects:

[0044] The utility model provides a roadbed reinforcement construction equipment, wherein the mounting seat 2 and the guide sleeve 6 support and guide the adjustment rod 8; the handle serves as the fulcrum of the sliding adjustment rod 8; the position of the blocking reversal block 7 relative to the ratchet 5 can be adjusted by sliding the adjustment rod 8, and the operator can quickly judge whether the blocking reversal block 7 is in a state of abutting against the ratchet 5 or the blocking reversal block 7 is completely away from the ratchet 5 through the position of the first limit block 9 and the second limit block 10 relative to the mounting seat 2. When the blocking reversal block 7 abuts against the ratchet 5, it locks the wheel shaft 3 so that it can only rotate in one direction, so as to prohibit the tire from rotating in the backward direction, thereby preventing the equipment from retreating on the slope. If the equipment is in the construction state at this time, the equipment can be stably stopped on the slope; if the equipment is in the climbing state at this time, the operator can stop and rest at any time, which is more convenient to use. When the equipment is located on flat ground, the blocking reversal block 7 completely leaves the ratchet 5, and the equipment can move freely forward and backward, which is convenient to use.
