Description

Technical Field

[0001] The utility model relates to the field of road guardrails, in particular to a road concrete guardrail casting device. Background Art

[0002] Concrete guardrails on the road are mainly used to reduce the energy of vehicle collisions, protect vehicles and passengers from injury, and prevent vehicles from running off the road or running into the opposite lane, causing traffic chaos and even leading to more accidents.

[0003] Concrete guardrail is formed by pouring concrete into the casting mold of the guardrail by a concrete transport vehicle and then solidifying the concrete. The casting mold is fixed with side panels and end panels on both sides. In order to prevent the side panels on both sides of the casting mold from being squeezed and deformed by concrete, several corresponding connecting clips are fixed on the side panels on both sides. The connecting rod between the two connecting clips is used to tighten the side panels. In order to facilitate the pouring of the concrete transport vehicle and prevent the material from spilling, a receiving trough is placed on the upper part of the casting mold to receive the concrete material. However, due to the long length of the casting mold and the limitation of the pull rod, the receiving trough needs to be manually lifted for shifting and transportation when pouring at different positions, and then pouring is carried out after the shift. This makes the pouring unable to operate continuously, affecting the construction efficiency of the pouring, and the workers' operation is more laborious and laborious with high labor intensity.

[0004] In order to solve the above-mentioned problems, the utility model provides a road concrete guardrail casting device.

[0005] The utility model is realized through the following technical solutions:

[0006] A road concrete guardrail casting device comprises a casting mould with an opening at the top, the top of the casting mould is fixed by a plurality of tie rods, the top of the casting mould is supported by a movable support frame which can cross the tie rods and move, and the movable support frame is movably supported by a receiving trough for casting concrete into the casting mould.

[0007] Further optionally, the movable support frame includes two longitudinally arranged connecting rods, the two connecting rods are transversely connected to a plurality of support rods for supporting the bottom of the material receiving trough, and the ends of the two connecting rods are respectively fixed with support legs for supporting the sides of the material receiving trough.

[0008] Further optionally, a fixing rod which is integrally and obliquely arranged is provided at the lower part of the supporting leg, and the fixing rod is connected to a supporting wheel supported on the side plate of the casting mold through a supporting shaft.

[0009] Further optionally, the support leg and the fixing rod are bent outward as a whole and protrude to cross the end of the pull rod.

[0010] Further optionally, a circle of support grooves is provided in the center of the outer ring of the support wheel and is clamped on the outer edge of the side plate of the casting mold.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0018] like Figure 1 As shown, a road concrete guardrail casting device includes a casting mold 1 with an opening on the top. The top of the casting mold 1 is fixed by a plurality of tie rods 3. The top of the casting mold 1 is supported by a movable support frame that can cross the tie rods 3 and move. The movable support frame is supported by a receiving trough 4 for casting concrete on the casting mold 1. The movable receiving trough 4 can be replaced, and the receiving trough 4 with different length specifications can be used for better versatility.

[0019] like Figure 3 As shown, the movable support frame includes two longitudinally arranged connecting rods 7, and the two connecting rods 7 are transversely connected to multiple support rods 12 for supporting the bottom of the receiving trough 4. The cross-section of the support rods 12 is conical, which reduces the obstruction of concrete materials and facilitates the falling of concrete materials. The ends of the two connecting rods 7 are respectively fixed with support legs 8 for supporting the sides of the receiving trough 4.

[0020] like Figure 2 As shown, an integral and inclined fixing rod 9 is provided at the lower part of the supporting leg 8 , and the fixing rod 9 is connected to a supporting wheel 10 supported on the side plate of the casting mold 1 through a supporting shaft.

[0021] like Figure 2 As shown, the support leg 8 and the fixing rod 9 are bent outward as a whole and protrude and cross the end of the pull rod 3, so that the support leg 8 and the fixing rod 9 will not interfere with the end of the pull rod 3, and the movable support frame can cross the pull rod 3 when moving.

[0022] like Figure 2 As shown, a support groove 11 is provided in the center of the outer ring of the support wheel 10 and is clamped on the outer edge of the side plate of the casting mold 1. The support groove 11 can be clamped on the outer edge of the side plate of the casting mold 1 to prevent the support wheel 10 from falling off.

[0023] like Figure 3 As shown, handles 5 are fixed to the front and rear ends of the material receiving trough 4, and a plurality of support slots 6 matching the support rods 12 are opened at the bottom of the material receiving trough 4. The support slots 6 are connected to the support rods 12 to prevent the material receiving trough 4 from being separated from the movable support frame.

[0024] The implementation principle of a road concrete guardrail casting device in the embodiment of the present application is:

[0025] During pouring, the four inclined support wheels 10 with support grooves 11 at the bottom of the mobile support frame are clamped on the outer edge of the side plate of the casting mold 1 to realize the installation of the mobile support frame. After installation, the receiving trough 4 is placed on the mobile support frame, and the multiple support slots 6 at the bottom of the receiving trough 4 are clamped on the support rods 12 of the corresponding mobile support frame for positioning to prevent the receiving trough 4 from being dislocated;

[0026] Then the concrete transport truck pours the concrete on the receiving trough 4 (the operator holds the handle 5 to prevent the receiving trough 4 from moving), and enters the casting mold 1 through the lower outlet of the receiving trough 4 to realize the casting of concrete. After the casting of one area is completed, the operator holds the handle 5 to move the receiving trough 4, and moves the position on the casting mold 1 through the lower mobile support frame. The concrete transport truck continues to pour while moving slowly. In this way, when pouring different positions of the casting mold 1, the receiving trough 4 supported on the casting mold 1 can move with the mobile support frame, thereby realizing the continuous casting operation of the casting mold 1, greatly improving the efficiency of concrete guardrail casting, and the moving receiving trough 4 does not need to be manually lifted and transported, which is time-saving and labor-saving for the operator and is more convenient.
