Description

Technical Field

[0001] The utility model relates to the technical field of cement pipe transportation, in particular to a cement pipe transportation protection device. Background Art

[0002] The cement pipe body is used in municipal drainage projects. It is roughly a cylindrical shape with a hollow interior and open ends. In order to facilitate splicing between two cement pipe bodies, one end of the cement pipe body is set to a flared shape during production to facilitate the insertion and splicing between the two cement pipe bodies. Since one end of the existing cement pipe body is set to a flared shape, during transportation, the cement pipe body is limited by its own shape and cannot be placed horizontally on the vehicle board. It is placed in an inclined state on the vehicle board, with only two supporting points in contact with the vehicle board, and the contact area is small. When the road surface is bumpy, the two supporting points of the cement pipe body are subjected to a large pressure and are easily broken. Based on the above situation, it is necessary to design a cement pipe transportation protection device to solve the above problem. Utility Model Content

[0003] The utility model provides a cement pipe transportation protection device to solve the problem in the prior art that the cement pipe body cannot be placed horizontally on a vehicle plate during transportation, resulting in a small contact area between the cement pipe body and the vehicle plate, a large pressure on the supporting point, and easy damage.

[0004] The technical problem solved by the utility model is achieved by the following technical solutions:

[0005] A cement pipe transportation protection device includes a load-bearing plate installed on a vehicle plate, the load-bearing plate includes a rigid base and a flexible support layer fixed on the rigid base, the flexible support layer is recessed to form a receiving groove capable of horizontally placing a cement pipe body with a flared portion at one end, and the rigid base of the load-bearing plate is fixed to the vehicle plate by a fastener.

[0006] Preferably, the accommodating groove of the flexible supporting layer on the supporting plate is defined by a first contact surface that contacts the end face of the cement pipe body away from the flared portion, a second contact surface that contacts one end of the flared portion of the cement pipe body, and an arc-shaped contact surface that contacts the lower part of the cement pipe body.

[0007] Preferably, the accommodating groove of the flexible supporting layer on the bearing plate is defined by a first contact surface that contacts the end surface of the cement pipe body away from the flared portion and an arc-shaped contact surface that only contacts the pipe body of the cement pipe body.

[0008] Preferably, an arch frame is detachably connected to the top of the bearing plate via a second fastener, and a flexible attachment layer that contacts the upper part of the cement pipe body is provided on the inner side of the arch frame.

[0009] Preferably, the second fastener includes a pin hole formed in the rigid base of the bearing plate, a pin inserted into the arch frame, and a spring sleeved on the outer surface of the pin. When the pin is inserted into the pin hole, the arch frame is stabilized above the bearing plate.

[0010] Preferably, the bearing plate is also detachably connected with a baffle for blocking the end face of the flared part of the cement pipe body through a third fastener. One side of the end face of the baffle close to the flared part of the cement pipe body is a flexible contact layer.

[0011] The beneficial effects of the present utility model are as follows: By arranging the bearing plate, the cement pipe body can be horizontally placed on the vehicle board, increasing the supporting area of the cement pipe body, avoiding excessive local stress on the bottom of the cement pipe body during transportation, resulting in damage to the cement pipe body. At the same time, by contacting the bottom of the cement pipe body with the flexible support layer, the condition of damage to the cement pipe body during transportation is further reduced.

Detailed implementation mode

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0021] Reference Figure 1 For the prior art of transporting the cement pipe body 1 of the present utility model, the existing cement pipe body 1 includes a pipe body 105 and a flared part 101. The flared part 101 is formed at one end of the pipe body 105, and the other end of the pipe body 105 is an insertion part 102. The diameter of the flared part 101 is larger than the diameter of the pipe body 105 of the cement pipe body 1, and the diameter of the insertion part 102 is equal to the diameter of the pipe body 105 of the cement pipe body 1. A stepped groove is also provided on the insertion part 102 for sleeving a rubber ring (not shown in the figure). Since the diameter of the flared part 101 is larger than the diameter of the insertion part 102, when two cement pipe bodies 1 are spliced and used, the insertion part 102 of one cement pipe body 1 can be easily inserted into the flared part 101 of another cement pipe body 1. When the cement pipe body 1 with the flared part 101 is placed on the car body panel 2, due to the limitation of its own shape, only two support points are in contact with the car body panel 2. The two support points are the first support point 103 and the second support point 104 respectively. When the cement pipe body 1 is transported in this posture, its support area is small. When encountering a bumpy road surface, the forces received by the two support points are large, and it is extremely easy to cause the problem of cement pipe breakage. Based on the above situation, the present utility model designs a cement pipe transportation protection device to solve the above problems.

[0022] Reference Figure 2 And Figure 3A cement pipe transportation protection device includes a bearing plate 3 installed on a vehicle plate 2 and capable of horizontally supporting a cement pipe body 1. The bearing plate 3 is a double-layer structure. The double-layer bearing plate 3 includes a rigid base 301 in contact with the vehicle plate 2 and a flexible supporting layer 302 covering and fixed on the rigid base 301. A receiving groove 303 is formed on the flexible supporting layer 302 and capable of horizontally supporting the cement pipe body 1 with an expanded portion 101 thereon. The receiving groove 303 can at least tightly adhere to the lower part of the tube body 105 of the cement pipe body 1 to fully ensure the supporting area of ​​the cement pipe body 1. The rigid base 301 of the bearing plate 3 can be fixed to the vehicle plate 2 by a fastener 4 to prevent the bearing plate 3 from shaking during bumps. The fastener 4 can be connected by bolts to fix the bearing plate 3 on the vehicle plate 2, or it can be fixed by other connection methods.

[0023] By providing the bearing plate 3, not only can the supporting area of ​​the cement pipe body 1 during transportation be enlarged to avoid excessive local force, but also the bottom of the cement pipe body 1 can be made to have flexible contact to avoid damage to the cement pipe body 1 when the cement pipe body 1 is bumpy during transportation.

[0024] Based on the implementation of the above solution, it is easy to think of the first embodiment of the utility model, referring to Figure 2 and Figure 3 The accommodating groove 303 that can support the lower part of the cement tube body 1 can be defined by three sides, namely, a first contact surface 3032 that contacts the end surface of the cement tube body 1 away from the flared portion 101, a second contact surface 3033 that contacts one end of the flared portion 101 of the cement tube body 1, and an arcuate contact surface 3031 that contacts the lower part of the cement tube body 1. The accommodating groove 303 formed by the three sides can make the lower part of the cement tube body 1 completely fit in the accommodating groove 303, that is, the flared portion 101 and the tube body 105 are both supported by the arcuate contact surface 3031, and the arcuate contact surface 3031 is the supporting surface for the cement tube body 1, so as to avoid the problem that the cement tube body 1 is easily damaged during transportation due to its small supporting area. The first contact surface 3032 and the second contact surface 3033 can prevent the relative displacement between the cement tube body 1 and the bearing plate 3 during acceleration and braking of the transport vehicle.

[0025] refer to Figure 4 , Figure 5 and Figure 6, which is the second embodiment of the present utility model. The receiving groove 303 capable of supporting the lower part of the pipe body 105 of the cement pipe can be defined by enclosing it from two sides. The two sides are respectively a first abutting surface 3032 that abuts against the end surface of the cement pipe body 1 away from the flared portion 101 and an arc-shaped abutting surface 3031 that only contacts the pipe body 105 of the cement pipe body 1. The receiving groove 303 formed by enclosing these two sides can completely cover the lower part of the pipe body 105 of the cement pipe body 1 with the arc-shaped abutting surface 3031. In this embodiment, the arc-shaped abutting surface 3031 only supports the lower part of the pipe body 105 and does not support the flared portion 101. Similarly, it can also make the support area of the cement pipe body 1 large enough. The first abutting surface 3032 can abut against one end of the insertion portion 102 of the pipe body 105 to prevent the insertion portion 102 of the pipe body 105 from moving relative to the bearing plate 3.

[0026] On the basis of the second embodiment, in order to prevent the cement pipe body 1 from displacing due to inertia inside the receiving groove 303 during vehicle braking or acceleration, the present utility model improves the second embodiment. The bearing plate 3 is also detachably connected with a baffle 7 for blocking the end surface of the flared portion 101 of the cement pipe body 1 through a third fastener 8. The side of the baffle 7 close to the end surface of the flared portion 101 of the cement pipe body 1 is a flexible abutting layer 701. By providing the baffle 7, it can cooperate with the first abutting surface 3032 of the second embodiment to prevent the cement pipe body 1 from moving relative to the bearing plate 3 during transportation due to braking or acceleration. It should be noted that the third fastener 8 can be connected by the bolt fastening method as Figure 5 described, but it is not limited to the bolt fastening method.

[0027] As can be seen from the above, both the first embodiment and the second embodiment of the present utility model can achieve the protection of the cement pipe body 1 during transportation. The advantage of the first embodiment relative to the second embodiment is that its structure is simple and stable. The advantage of the second embodiment relative to the first embodiment is that during the later lifting and unloading process, since the flared portion 101 of the cement pipe body 1 in the second embodiment is not inside the receiving groove 303, the lifting rope can be wound around the flared portion 101 for lifting. Therefore, the advantage of the second embodiment relative to the first embodiment is that it is convenient for lifting and unloading. The disadvantage of the second embodiment relative to the first embodiment is that it needs to cooperate with the baffle 7 to limit the displacement of the cement pipe body 1 relative to the bearing plate 3. Therefore, its overall structure is relatively complex compared to the first embodiment.

[0028] On the basis of the first and second embodiments, in order to prevent the cement tube body 1 from shaking up and down on a bumpy road surface, causing the cement tube body 1 to escape from the receiving groove 303, the utility model adds an arch frame 5 on the basis of the first and second embodiments to limit the cement tube body 1 from shaking up and down on the bearing plate 3. The upper part of the bearing plate 3 is also detachably connected with the arch frame 5 by a fastener 26. The inner side of the arch frame 5 is provided with a flexible attachment layer 501 that contacts the upper part of the cement tube body 1. After the arch frame 5 is fixed to the bearing plate 3, the flexible attachment layer 501 contacts the upper part of the cement tube body 1 to prevent the cement tube body 1 from shaking up and down, and the flexible attachment layer 501 can form a flexible contact with the cement tube body 1 to prevent the cement tube body 1 from breaking.

[0029] Specifically, the fastener 2 6 used to connect the bearing plate 3 and the arch frame 5 above adopts a connection method of a pin rod 61 and a pin hole 603. The connection method of the pin rod 61 and the pin hole 603 has the effect of being able to be quickly plugged in and out, and is more convenient to use. The fastener 2 6 includes a pin hole 603 opened on the rigid base 301 of the bearing plate 3, a pin rod 61 inserted on the arch frame 5, and a spring 602 sleeved on the outer surface of the pin rod 61. When the pin rod 61 is engaged with the pin hole 603, the arch frame 5 is stabilized above the bearing plate 3.

[0030] It should be noted that, in the above, the flexible supporting layer 302 , the flexible resisting layer 701 and the flexible attaching layer 501 are all supported by materials with flexible properties, such as rubber, cloth and the like.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
