[0001] This utility model belongs to the field of concrete treatment technology, and more specifically, it relates to a concrete curing device for bridge piers and abutments. Background Technology

[0002] Bridge piers are made of concrete, which may develop cracks after long-term weathering. They need to be maintained and repaired to prevent the cracks from widening and reducing the strength of the piers. Generally, the cracks are filled by manual coating.

[0003] Based on the above, the current curing equipment uses plastic bags or cylindrical pushers to hold the concrete, which makes it inconvenient to control the uniform delivery of the concrete. It also requires the use of a separate applicator for application, resulting in low work efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a concrete curing device for bridge piers and abutments. This addresses the issues raised in the background section regarding existing curing devices that use plastic bags or cylindrical pushers to hold the concrete, making it inconvenient to control the uniform delivery of the concrete and requiring separate application with a smearing tool, resulting in low work efficiency.

A screw propeller is rotatably installed between the front cover and the rear cover, and the rear end of the shaft of the screw propeller extends out of the rear cover. A support seat is fixedly installed at the bottom of the curing cylinder, and a fixed handle is fixedly installed at the rear bottom of the support seat. A concrete hopper is connected to the top of the curing cylinder by a threaded connection.

[0007] Furthermore, the outer front end of the output tube has an external thread structure; the rear end of the discharge control device has an internal thread structure, and the discharge control device is fixed to the outside of the output tube by a threaded connection.

[0008] Furthermore, a ball valve chamber is integrally provided on the upper rear of the output pipe, a valve cover is fixedly provided on the top of the ball valve chamber, a ball valve core is slidably provided inside the ball valve chamber, a groove is provided in the middle of the top of the ball valve core, and a spring is provided between the groove on the top of the ball valve core and the bottom of the valve cover.

[0009] Furthermore, a linkage shaft is rotatably provided on the rear side of the rear end cover, and the top end of the linkage shaft is connected to the rear end of the screw propeller by a bevel gear transmission; an internal ratchet gear is fixedly provided at the bottom end of the linkage shaft.

[0010] Furthermore, two sets of spring rods are fixedly installed on the front side of the fixed grip, and a pressing handle is slidably installed outside the spring rods; a spring is sleeved on the outside of each spring rod and a baffle is fixedly installed through the pressing handle.

[0011] Furthermore, a rack is fixedly installed on the upper rear side of the pressing handle, and the rack meshes with an internal ratchet gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model is convenient and efficient to operate. Through the detachable installation design of the concrete hopper and the curing device cylinder, combined with the automatic material feeding structure, it realizes the rapid filling of concrete.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a concrete curing device for bridge piers, including a curing device cylinder 1, a front cover 2 fixedly installed at the front end of the curing device cylinder 1; an output pipe 201 integrally installed on the lower front side of the front cover 2, and a discharge control device 3 fixedly installed at the front end of the output pipe 201; a rear cover 4 fixedly installed at the rear end of the curing device cylinder 1; a screw propeller 5 rotatably installed between the front cover 2 and the rear cover 4, with the rear end of the shaft of the screw propeller 5 passing through the rear cover 4; a bearing seat 101 fixedly installed at the bottom of the curing device cylinder 1, and a fixed handle 6 fixedly installed on the rear bottom side of the bearing seat 101; and a concrete hopper 8 connected to the top of the curing device cylinder 1 by a threaded connection.

[0028] The front end of the output tube 201 has an external thread structure; the rear end of the discharge control device 3 has an internal thread structure, and the discharge control device 3 is fixed to the outside of the output tube 201 by a threaded connection.

[0029] Among them, a ball valve chamber 202 is integrally provided on the upper rear of the output pipe 201, a valve cover 203 is fixedly provided on the top of the ball valve chamber 202, a ball valve core 204 is slidably provided inside the ball valve chamber 202, a groove is provided in the middle of the top of the ball valve core 204, and a spring is also provided between the top groove of the ball valve core 204 and the bottom of the valve cover 203.

[0030] Among them, a linkage shaft 401 is rotatably provided on the rear side of the rear end cover 4, and the top end of the linkage shaft 401 is connected to the rear end of the screw propeller 5 by a bevel gear transmission; an internal ratchet gear 402 is fixedly provided at the bottom end of the linkage shaft 401.

[0031] Two sets of spring rods 601 are fixedly installed on the front side of the fixed grip 6, and a pressing handle 602 is slidably installed on the outside of the spring rods 601; a spring is sleeved on the outside of each spring rod 601 and a baffle is fixedly installed through the pressing handle 602.

[0032] Among them, a rack 7 is fixedly installed on the upper rear side of the pressing handle 602, and the rack 7 meshes with the internal ratchet gear 402.

[0033] Pouring and Installation: Pour concrete into concrete tank 8 beforehand, and seal the concrete tank 8 with the opening facing upwards using a threaded cap.

[0034] When using, first remove the threaded cap, flip the curing device cylinder 1 downwards, install the concrete hopper 8 on the outside of the curing device cylinder 1, and then stand the curing device cylinder 1 upright. The concrete will automatically fall into the curing device cylinder 1.

[0035] Concrete conveying: Pull the pressing handle 602 backward to drive the rack 7 forward, which in turn drives the inner ratchet gear 402 to rotate. The inner ratchet gear 402 cooperates with the bevel gear through the linkage shaft 401 to make the screw propeller 5 start to rotate.

[0036] The propulsive force generated by the screw propeller 5 pushes the concrete through the ball valve chamber 202, opens the ball valve core 204, enters the discharge controller 3, and is output from its front end.

[0037] After the pressing handle 602 is released, the spring outside the spring rod 601 automatically resets the pressing handle 602, and at the same time drives the rack 7 to reset. At this time, the inner ratchet gear 402 rotates freely, and the linkage shaft 401 stops rotating, ensuring that the concrete moves only in one direction along the conveying direction.

[0038] Example 2:

[0039] Material discharge shape control: The material discharge shape control device 3 adopts a threaded connection, which can be quickly disassembled and replaced according to actual needs;

[0040] Its shape can be customized, including but not limited to flared, square or irregular shapes. When using it, the material discharge controller 3 is attached to the crack of the bridge pier to carry out concrete coating.

[0041] The specific usage and function of this embodiment are as follows:

[0042] In this utility model, when in use, concrete is poured into the concrete tank 8 in advance, the opening of the concrete tank 8 is placed facing upward and a threaded cap is installed for sealing. When in use, the threaded cap is removed, the curing device cylinder 1 is flipped downward, the concrete tank 8 is installed outside the curing device cylinder 1, and then the curing device cylinder 1 is stood up.

[0043] The concrete will automatically fall from the concrete hopper 8 into the curing cylinder 1;

[0044] Pull the pressing handle 602 backward to advance the rack 7. The rack 7 drives the inner ratchet gear 402 to rotate, which in turn drives the linkage shaft 401 to rotate. The linkage shaft 401, in conjunction with the bevel gear, drives the screw propeller 5 to rotate. The screw propeller 5 generates a propulsive force to transport the concrete forward. The concrete passes through the ball valve chamber 202, opens the ball valve core 204, and is delivered into the discharge control device 3, from which it is output from the front end of the discharge control device 3. Place the discharge control device 3 against the crack in the bridge pier to apply the concrete.

[0045] After the pressing handle 602 is released, the pressing handle 602 automatically resets through the spring outside the spring rod 601, the rack 7 automatically resets, and drives the inner ratchet gear 402 to rotate freely, while the linkage shaft 401 does not rotate, ensuring that the concrete is only conveyed forward.

[0046] The shape of the discharge control device 3 can be customized as needed, such as a flared mouth, a square mouth, or an irregularly shaped mouth. The discharge control device 3 is connected by a thread and can be quickly disassembled and replaced.
