Description

Technical Field

[0001] This utility model belongs to the field of concrete curing technology, and specifically relates to a concrete curing device. Background Technology

[0002] Concrete curing involves artificially creating specific humidity and temperature conditions to allow freshly poured concrete to harden and strengthen normally or at an accelerated pace. The gradual hardening and strength gain of concrete is a result of cement hydration, which requires specific temperature and humidity conditions. If these conditions are not present in the surrounding environment, artificial curing of the concrete is necessary.

[0003] Existing technology CN218149947U discloses a concrete curing device, including a main board. A housing is fixedly connected to the upper surface of the main board, and a water tank is fixedly connected to the middle of the upper surface of the main board. A feeding trough is provided in the rear middle part of the top wall of the housing, and placement troughs are connected to both sides of the feeding trough. A pull rod is slidably connected to the middle of the rear side of the top wall of the housing, and a cutting blade is fixedly connected to the lower end of the pull rod. A cutting groove is provided on the rear side of the top wall of the main board, and the cutting blade is located directly above the cutting groove. A water pump is fixedly connected to the bottom of the water tank, and the water pump is connected to the top of a water outlet plate through a water pipe. The water outlet plate is hollow and connected to the water pipe. In this invention, the pull rod pushes downward to drive the cutting blade below, making it easier for workers to cut materials and reducing their workload. The water pump sprays water from the water tank onto the ground through atomizing nozzles, which can increase the curing effect.

[0004] However, in this device, the cutting blade is set vertically, while the curing membrane has high toughness. Cutting in the vertical direction can easily result in incomplete cutting. Therefore, we propose a concrete curing device to solve the above problems. Utility Model Content

Detailed Implementation

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1:

[0025] like Figure 1-4 As shown, a concrete curing device includes a film-laying trolley 100, a film-pressing roller 101 at the front end of the film-laying trolley 100, a film-covering shaft 102 and a water outlet assembly 103 arranged sequentially at the rear end of the film-laying trolley 100, and a cutting mechanism located between the film-pressing roller 101 and the film-covering shaft 102 at the front end of the film-laying trolley 100.

[0026] The cutting mechanism includes a first slide bar 200, a slider 201, a blade 202, and a pressing assembly. A cutting groove 203 is provided at the front of the film-laying trolley 100. Two first slide bars 200 are provided on the upper part of the cutting groove 203. A slider 201 is slidably mounted on the outer side of the two first slide bars 200. The blade 202 is fixedly mounted on the lower end of the slider 201 and is located inside the cutting groove 203. A fiber optic cable 204 is fixedly connected to the right end of the slider 201 and slides through the right side of the film-laying trolley 100. A reset cable 205 is fixedly connected to the left end of the slider 201 and slides through the left side of the film-laying trolley 100 and is connected to a spiral spring 206.

[0027] The first slide bar 200 is used to support the slider 201, the slider 201 is used to support the blade 202, the blade 202 is used to cut the film, the cutting groove 203 provides space for the blade 202 to slide, the pull rope 204 is used to pull the slider 201, thereby pulling the blade 202, the reset rope 205 is used to pull the slider 201 and the blade 202 to reset, so that when the slider 201 and the blade 202 are not pulled, the slider 201 and the blade 202 stay at the leftmost end, and the spiral spring 206 provides power for the reset of the slider 201 and the blade 202.

[0028] A pull ring 207 is fixedly fitted to the right end of the fiber optic cable 204 to facilitate pulling the fiber optic cable 204.

[0029] The cutting groove 203 is symmetrically provided with limiting plates 208 at the rear of both ends. The limiting plates 208 can prevent the film from touching the blade 202 and the pressing component during the laying process.

[0030] The film-laying trolley 100 is equipped with a pull handle 104 at the rear end for easy pulling of the film-laying trolley 100.

[0031] In this embodiment, when the film needs to be cut after it has been laid out, the pressing component is used to press the film to prevent it from sliding. Then, the fiber optic cable 204 is pulled, which pulls the slider 201 and the blade 202 to slide from left to right. During the sliding process, the blade 202 contacts and cuts the taut film, so that the film is cut. When the slider 201 is pulled to the rightmost end, the film is completely cut. At this time, the fiber optic cable 204 is released, and the spiral spring 206 pulls the slider 201 and the blade 202 back to the initial position through the reset cable 205, thus completing the cutting.

[0032] In this embodiment, by setting a cutting mechanism, the membrane can be cut by the blade 202 sliding left and right, ensuring that the membrane can be completely cut and avoiding the problem of the membrane not being completely cut due to its toughness when cutting from top to bottom.

[0033] Example 2:

[0034] like Figure 1-4 As shown, based on Embodiment 1, a concrete curing device is further described. The pressing assembly includes a second sliding rod 300, a bidirectional threaded rod 301, a pressure plate 302, and a return spring 303. The second sliding rod 300 and the bidirectional threaded rod 301 are sequentially mounted on the front side of the cutting groove 203, and the right side of the bidirectional threaded rod 301 rotates through the right side of the film-laying trolley 100. Two inclined pressure blocks 304 are symmetrically mounted on the outer sides of the second sliding rod 300 and the bidirectional threaded rod 301. Two spring grooves located on the lower side of the bidirectional threaded rod 301 are symmetrically opened on the left and right sides of the film-laying trolley 100. A return spring 303 is installed inside each of the two spring grooves. The pressure plate 302 is mounted on the upper end of the two return springs 303, and the upper sides of the left and right ends of the pressure plate 302 correspond to the inclined pressure blocks 304.

[0035] The bidirectional threaded rod 301 is threadedly connected to the inclined pressure block 304. The second slide rod 300 is used for positioning. The pressure plate 302 is a rectangular plate with a hollow center, and the hollow part corresponds to the cutting groove 203. The upper sides of the left and right ends of the pressure plate 302 are provided with inclined protrusions corresponding to the inclined pressure block 304. The inclined protrusions can abut against the inclined pressure block 304. In this way, when the inclined pressure block 304 moves towards the end of the bidirectional threaded rod 301, it can abut against the inclined protrusions, causing the pressure block 304 to move down and press the film.

[0036] A rotating handle 305 is fixedly mounted on the right end of the bidirectional threaded rod 301 to facilitate rotation of the bidirectional threaded rod 301.

[0037] In this embodiment, when pressing the film, the bidirectional threaded rod 301 is rotated, causing the inclined pressure blocks 304 on both sides of the bidirectional threaded rod 301 to move towards their ends, thereby pressing the pressure blocks 304 and causing the pressure blocks 304 to press down on the film, thus fixing the film.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
