Description

Technical Field

[0001] This invention relates to the field of municipal road construction, and in particular to a manhole protection device for road inspection wells. Background Technology

[0002] Municipal road construction is often accompanied by the construction of urban underground pipe networks. On the one hand, after the underground pipe network construction is completed, manhole covers can only be installed after the roadbed, subgrade, base course, and surface course construction are completed. On the other hand, when multiple municipal roads in the urban area are under construction simultaneously, in order to minimize the impact on existing traffic, traffic is opened randomly after the base course construction is completed in some cases.

[0003] Under these conditions, if road manholes are not covered in a timely manner or are not properly covered, they can easily pose safety hazards or even cause accidents.

[0004] Traditional wellhead protection devices typically use water-filled barriers or enclosures. These two types of devices are bulky and cannot be adjusted according to the diameter of the wellhead. If too few are installed, maintenance will be inadequate, and if too many are installed, traffic will be obstructed. These issues need to be addressed. Summary of the Invention

DETAILED DESCRIPTION

[0030] The application will be further described in detail below in combination with the drawings.

[0031] As shown in Figure 1 , Figure 2 , a well mouth guard device for a road surface inspection well comprises a pair of support seats 1, a sliding rod 2, a support rod 3, a guard rod 4, and a driving mechanism 5.

[0032] As shown in Figure 1 , Figure 2As shown in the drawings, the pair of support bases 1 are circular plate-shaped and arranged in two layers. The lower end surface of the lower support base 1 is provided with universal wheels 11, so that the movement and transfer of the protective device are more convenient.

[0033] As shown in the drawings, Figure 1 , Figure 2 , Figure 3 The sliding rod 2 is horizontally and slidingly connected to the side wall of the support base 1 and slides along the diameter direction of the support base 1. The support rod 3 is arranged in a circular arc shape at the outer end of the sliding rod 2, and when the sliding rod 2 is retracted, a plurality of support rods 3 form a circular ring. The anchor rod 31 for piercing the ground is vertically and slidingly connected to the lower support rod 3, so as to realize the fixation of the protective device.

[0034] As shown in the drawings, Figure 1 , Figure 2 The protective rod 4 is vertically arranged between the upper and lower support rods 3, and is used for maintaining vehicles or pedestrians. The driving mechanism 5 is arranged between the pair of support bases 1 and is used to control the horizontal sliding of the sliding rod 2.

[0035] As shown in the drawings, Figure 1 , Figure 2 , Figure 3 The driving mechanism 5 includes a pair of rotating discs 51, a connecting pipe 52 and a guide block 53. The rotating disc 51 is coaxially and rotatingly connected to the side of the support base 1 close to each other, and the connecting pipe 52 is vertically fixed between the pair of rotating discs 51 and is used to control the synchronous rotation of the pair of rotating discs 51.

[0036] As shown in the drawings, Figure 3 , Figure 4 The guide block 53 is arranged on the upper end surface of the inner end of the sliding rod 2, and the support base 1 is provided with a guide hole 12 which slides along the diameter direction thereof and is used for the sliding of the guide block 53. The rotating disc 51 is provided with a circular arc-shaped limiting hole 54 which gradually diverges from the inside to the outside, and the guide block 53 penetrates the limiting hole 54, and when the rotating disc 51 rotates, the limiting hole 54 can push the guide block 53 and the sliding rod 2 to slide.

[0037] When using the protective device, first control the rotation of the connecting pipe 52, at this time the connecting pipe 52 drives the rotating disc 51 to rotate synchronously, at this time under the cooperation of the limiting hole 54 on the rotating disc 51 and the guide block 53, the guide block 53 slides outward and drives the sliding rod 2 and the support rod 3 to move synchronously, so as to realize the expansion of the support rod 3, and the circular ring area space surrounded by the support rod 3 is expanded.

[0038] Until the circular ring area space is larger than the diameter of the inspection well or the construction site area, the whole protective device is lifted on the well mouth of the inspection well, at this time the support rod 3 and the sliding rod 2 are horizontally supported on the ground, and the anchor rod 31 is controlled to pierce the ground, realizing the fixation of the whole protective device.

[0039] Therefore, by setting the adjustable protection device, it is suitable for different caliber inspection wells or other construction sites, and the protection device can be reasonably arranged according to the range of the inspection well or the construction site, which can meet the protection requirements and will not occupy too much lane, and can prevent the problem of not strict maintenance or hindering traffic.

[0040] As shown in Figure 2 , Figure 5 , the side wall of the protection rod 4 at one end of the support rod 3 is rotatably connected with the elastic telescopic rod 41, and the outer wall of the protection rod 4 at the other end is provided with a recess hole 42 for inserting the telescopic rod 41. The protection rod 4 is provided with a receiving groove 43 for embedding the telescopic rod 41 after being turned over, and the receiving groove 43 is provided with a clamping block 44 for clamping the telescopic rod 41.

[0041] When the support rod 3 is unfolded, there is a gap between the adjacent support rods 3, at this time, the telescopic rod 41 is controlled to turn out of the receiving groove 43, then the telescopic rod 41 is controlled to shrink, and is aligned with the recess hole 42 on the protection rod 4 on the other side, then the telescopic rod 41 is loosened, so that the telescopic rod 41 is inserted into the recess hole 42, and a transverse interception is formed between the protection rods 4 on the adjacent two support rods 3, thereby ensuring the protection effect of the protection device.

[0042] As shown in Figure 3 , the connecting pipe 52 includes an upper pipe 55 and a lower pipe 56, the upper end of the lower pipe 56 is provided with an insertion pipe 57 for inserting the upper pipe 55, the outer wall of the insertion pipe 57 is provided with a gear ring 58, and the inner wall of the upper pipe 55 is provided with a gear ring 59 which is engaged with the gear ring 58, so that the upper pipe 55 and the lower pipe 56 can rotate synchronously and can relatively slide vertically during rotation.

[0043] As shown in Figure 3 , Figure 5 , the outer wall of the lower pipe 56 is rotatably connected with a forward and reverse ratchet handle 6, which is used for conveniently controlling the rotation of the lower pipe 56. The protection rod 4 includes an upper rod 45 and a lower rod 46, the upper rod 45 is vertically slidably connected to the lower rod 46, so as to realize the free adjustment of the length of the protection rod 4.

[0044] As shown in Figure 3 , the connecting pipe 52 is provided with a control mechanism 7 for controlling the vertical movement of the upper support seat 1, the control mechanism 7 includes a pair of lead screws 71, a pair of gantry frames 72, a driving gear 73 and a driven gear 74.

[0045] As shown in Figure 3 , the lead screw 71 is vertically rotatably connected to the lower support seat 1 and located on both sides of the connecting pipe 52. The gantry frame 72 is arranged on the upper support seat 1 and is threadedly connected with the lead screw 71. The driving gear 73 is arranged on the outer wall of the connecting pipe 52, and the driven gear 74 is arranged on the lead screw 71 and engaged with the driving gear 73.

[0046] When the area needing maintenance is larger, the danger coefficient is larger, at this time the working height of the protection device needs to be higher, on the contrary, when the area needing maintenance is smaller, the danger coefficient is smaller, at this time the working height of the protection device does not need to be too high.

[0047] Therefore, when the rotation of the connecting pipe 52 drives the sliding rod 2 and the support rod 3 to expand outward, the connecting pipe 52 drives the driving gear 73 to rotate synchronously, at this time the rotating gear drives the driven gear 74 and the lead screw 71 to rotate, at this time the lead screw 71 controls the gantry 72 and the upper support seat 1 to move upward, realizing the adjustment of the spacing between the support seats 1.

[0048] When the upper support seat 1 slides upward, the upper pipe 55 and the lower pipe 56 can rotate synchronously and vertically displace in the process of rotation, and at the same time the upper rod 45 vertically moves relative to the lower rod 46, so as to realize the vertical adjustment of the whole protection device.

[0049] The height reduction adjustment method of the protection device is opposite, which is not described herein. At the same time, the protection area of the protection device is proportional to the protection height, so that the synchronous adjustment of the two can be realized, making the use process more convenient.

[0050] Therefore, by setting the height-adjustable protection device, the larger the construction site range is, the higher the protection height of the protection device is, so as to ensure the safety of the construction site.

[0051] The specific embodiments are only an explanation of the present application, which is not a limitation of the present application, and the person skilled in the art can make a modification without creative contribution according to the need after reading the present specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
