Description

Technical Field

[0001] This utility model belongs to the field of power pole manufacturing technology, specifically relating to a release agent spraying device. Background Technology

[0002] Cement utility poles are components formed using mold casting, which consists of an upper mold and a lower mold. During the casting process, a release agent is sprayed onto the inner wall of the mold. This release agent is a functional substance that acts as an intermediary between the mold and the finished product, facilitating the removal of the formed product from the mold. Spraying the release agent onto the inner wall of the cement pole mold creates a barrier between the mold's inner wall and the cement concrete, making it easier to open the mold later to remove the finished cement utility pole and to reuse the mold.

[0003] Existing technologies disclose release agent spraying devices, such as the novel release agent spraying device for cement utility poles disclosed in patent CN210097996U, which includes a plunger pump and its drive motor. The outlet end of the plunger pump is connected to a handheld spray nozzle via a flexible hose. A clamping sleeve is fitted onto the handheld spray nozzle, and a V-shaped frame is fixed to the outer wall of the clamping sleeve. Wheels are provided at both ends of the V-shaped frame, and guide wheels are provided at the outer ends of the wheels. In use, the guide wheels are engaged with the two edges of the utility pole mold, and the spray nozzle of the handheld spray nozzle is fixed directly above the utility pole mold by the V-shaped frame and the wheels. Pushing the handheld spray nozzle forward, the spray nozzle moves along the trajectory of the center of the top of the utility pole mold to spray the release agent. It is simple to use and overcomes the disadvantages of uneven application and time-consuming and labor-intensive methods caused by traditional mopping of release agent.

[0004] Undeniably, the novel cement pole release agent spraying device disclosed in this patent can achieve the aforementioned effects, but it also has certain shortcomings: when the operator holds the spray nozzle and pushes it along the pole mold, uneven pushing force (such as fluctuating speed) can result in localized areas of the mold's inner wall being sprayed too thinly or too thickly, affecting the uniformity of the release agent spraying. Moreover, in actual production, the pole mold is quite long, and relying solely on the operator to continuously push the spray nozzle for extended periods can easily lead to fatigue, further reducing the stability of pushing the nozzle along the pole mold and also decreasing the release agent spraying efficiency.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a release agent spraying device to solve the problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A mold release agent spraying device, comprising:

[0009] Walking track;

[0010] A traveling trolley that moves along the aforementioned travel track;

[0011] The spray booth is located in the middle of the travel track;

[0012] The spraying structure located in the spraying chamber includes a release agent tank, a diaphragm pump with its inlet end connected to the bottom of the release agent tank, a delivery pipe with its inlet end connected to the outlet end of the diaphragm pump and its outlet end extending into the spraying chamber, an arc-shaped guide pipe with its middle section connected to the outlet end of the delivery pipe and sealed at both ends, and a plurality of nozzles evenly spaced on the guide pipe; wherein, a fixing rod is fixed at each end of the guide pipe, and the outer end of the fixing rod is fixed to the inner wall of the spraying chamber by bolts.

[0013] Furthermore, the travel track consists of two parallel, spaced-apart channel steels, with the webs of the two channel steels close to each other.

[0014] Furthermore, the traveling trolley includes a trolley body, multiple traveling wheels mounted on both sides of the trolley body with their outer walls contacting the top of the channel steel, multiple limiting wheels mounted on both sides of the bottom of the trolley body with their outer walls contacting the web of the channel steel, multiple support seats fixed at intervals on both sides of the top of the trolley body, a first winch fixed to the outer side of the starting end of the traveling track, and a second winch fixed to the outer side of the ending end of the traveling track; wherein, the outer end of the wire rope of the first winch is fixedly connected to the end of the trolley body near the starting end of the traveling track, and the outer end of the wire rope of the second winch is fixedly connected to the end of the trolley body away from the starting end of the traveling track.

[0015] Furthermore, fixing rings corresponding to the outer ends of the first winch wire rope and the second winch wire rope are fixed at both ends of the vehicle body.

[0016] Furthermore, the release agent spraying device also includes a cleaning structure disposed in the spraying chamber and located in front of the spraying structure. The cleaning structure includes a rotating rod extending through both ends of the spraying chamber, a plurality of arc-shaped follower rods evenly spaced and fixed in the middle of the rotating rod, a cleaning brush fixed on the outer wall of the follower rod, and a reduction motor fixed to the outer wall of the spraying chamber and connected to one end of the rotating rod via a coupling. A seated bearing is installed near the end of the rotating rod, and the seated bearing is fixed to the outer wall of the spraying chamber.

[0017] Furthermore, the guide tube is located inside the mold to be sprayed and a gap is left between the nozzle and the inner wall of the mold to be sprayed; the follower rod is located inside the mold to be sprayed and the outer end of the cleaning brush is attached to the inner wall of the mold to be sprayed.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This utility model uses a trolley to carry the mold along a track. The speed of movement is controlled by a winch, which can achieve uniform movement of the trolley. Compared with the manual pushing of a hand-held nozzle, the movement speed of the mold in the spraying chamber is more uniform. With the fixed nozzle position, the amount of release agent sprayed on different positions of the mold inner wall is uniform and consistent, avoiding local over-thickness or under-thickness, and improving the spraying quality of the release agent. In addition, even when facing a long utility pole mold, continuous spraying can be completed by the winch, avoiding the time-consuming, laborious and fatigue-prone problem of manually pushing with a hand-held nozzle. Secondly, the limiting wheel fits into the web of the channel steel, which can prevent the trolley from deviating during movement and ensure that the mold enters the spraying chamber in a straight line, which is convenient for subsequent cleaning and spraying.

[0020] (2) The spraying structure of this utility model adopts an arc-shaped guide tube and multiple nozzles are evenly spaced. The nozzles and the inner wall of the mold are reserved for fixing and spraying, which allows the release agent to be sprayed from multiple points at the same time, covering every area of ​​the inner wall of the mold, thus solving the problem of missed spraying that may exist in single-point spraying with a handheld sprayer.

[0021] (3) The present invention uses a diaphragm pump to pressurize and deliver the release agent. The pressure is stable and the output is uniform, which helps to ensure that the release agent is sprayed evenly on the inner wall of the mold.

[0022] (4) The cleaning structure added to this utility model drives the arc-shaped follower rod and cleaning brush to rotate through the reduction motor. The cleaning brush adheres to the inner wall of the mold, which can remove residual cement residue and dust and other impurities in the mold before spraying, so that the release agent is evenly attached and the surface quality of the cement rod after molding is guaranteed. Moreover, the mold moves with the trolley, first passing through the cleaning structure and then entering the spraying structure, realizing continuous operation of cleaning-spraying without the need for additional cleaning steps, which is conducive to improving the overall production efficiency.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Example

[0032] See appendix Figure 1-5 A mold release agent spraying device, comprising:

[0033] The traveling track 1 consists of two parallel and spaced channel steels 11 with their webs close to each other.

[0034] A traveling trolley 2 moves along the traveling track 1. The traveling trolley 2 includes a trolley body 21, multiple traveling wheels 22 installed on both sides of the trolley body 21 with their outer walls in contact with the top of the channel steel 11, multiple limiting wheels 23 installed on both sides of the bottom of the trolley body 21 with their outer walls in contact with the web of the channel steel 11, multiple support seats 24 fixed at intervals on both sides of the top of the trolley body 21, a first winch 25 fixed to the outer side of the starting end of the traveling track 1, and a second winch 26 fixed to the outer side of the ending end of the traveling track 1. The outer end of the wire rope of the first winch 25 is fixedly connected to the end of the trolley body 21 near the starting end of the traveling track 1, and the outer end of the wire rope of the second winch 26 is fixedly connected to the end of the trolley body 21 away from the starting end of the traveling track 1. In this embodiment, the two ends of the trolley body 21 are respectively fixed with fixing rings 27 corresponding to the outer ends of the wire ropes of the first winch 25 and the second winch 26. The outer ends of the winch wire ropes are fixed on the fixing rings 27 to realize the traction of the trolley body 21 by the winch.

[0035] The spray booth 3 is located in the middle of the travel track 1;

[0036] The spraying structure 4 is located in the spraying chamber 3. The spraying structure 4 includes a release agent tank 41, a diaphragm pump 42 with its inlet end connected to the bottom of the release agent tank 41, a delivery pipe 43 with its inlet end connected to the outlet end of the diaphragm pump 42 and extending into the spraying chamber 3, an arc-shaped guide pipe 44 with its middle section connected to the outlet end of the delivery pipe 43 and sealed at both ends, and multiple nozzles 45 evenly spaced on the guide pipe 44. Each end of the guide pipe 44 is fixed with a fixing rod 46, and the outer end of the fixing rod 46 is fixed to the inner wall of the spraying chamber 3 by bolts. It should be noted that... (See also...) Figure 2 The travel track 1 is located in the middle of the spraying chamber 3, the guide pipe 44 is located in the middle of the spraying chamber 3, and when the spraying structure 4 sprays the mold, the guide pipe 44 is located inside the mold to be sprayed and a gap is left between the nozzle 45 and the inner wall of the mold to be sprayed.

[0037] A cleaning structure 5 is installed inside the spray chamber 3 and located in front of the spray structure 4. The cleaning structure 5 includes a rotating rod 51 extending through both ends of the spray chamber 3, multiple arc-shaped follower rods 52 evenly spaced and fixed in the middle of the rotating rod 51, cleaning brushes 53 fixed on the outer wall of the follower rods 52, and a reduction motor 54 fixed to the outer wall of the spray chamber 3 and connected to one end of the rotating rod 51 via a coupling. A seated bearing 55 is installed near the end of the rotating rod 51 and is fixed to the outer wall of the spray chamber 3. It should be noted that... (See also...) Figure 2 When the coating mold enters the coating chamber 3, the follower rod 52 is located inside the coating mold and the outer end of the cleaning brush 53 is attached to the inner wall of the coating mold.

[0038] In use, the upper and lower molds of the cement pole are separated. Using an external gantry crane or other equipment, the mold to be sprayed is hoisted and placed on top of the vehicle body 21, with the inner cavity of the mold facing upwards. It should be noted that the mold in this application refers to either the upper or lower mold, that is, half of the entire cement pole mold, not the entire cement pole mold. The mold rests on the support bases 24 on both sides. The support bases 24 provide good support for the mold to be sprayed, thus stably placing the mold on top of the vehicle body 21. At this time, the vehicle body 21 is located at the starting end of the travel track 1, in the following state: Figure 1 As shown.

[0039] The second winch 26 is started to rotate forward while the first winch 25 rotates in the opposite direction. The wire rope of the second winch 26 generates a traction force on the vehicle body 21. Under this traction force, the vehicle body 21, carrying the mold, moves slowly and at a constant speed along the travel track 1 towards the spraying chamber 3. After the mold on the vehicle body 21 enters the spraying chamber 3, the reduction motor 54 is started. The reduction motor 54 drives the rotating rod 51 and the follower rod 52 to rotate, which in turn drives the cleaning brush 53 to rotate. During the rotation of the cleaning brush 53, it contacts the inner wall of the mold and cleans the residual residue and other impurities on the inner wall of the mold, so as to ensure the quality of the cement power pole products. The second winch 26 continues to pull the car body 21, which carries the mold towards the spraying structure 4. When the end of the mold is directly below the nozzle 45, the diaphragm pump 42 is started. The mold release agent in the mold release agent tank 41 is pumped into the delivery pipe 43 and the guide pipe 44 and finally atomized and sprayed out from the nozzle 45. The sprayed mold release agent is evenly sprayed onto the inner wall of the mold. Thus, as the second winch 26 pulls the car body 21, the cleaning structure 5 first cleans the inner wall of the mold, and then the spraying structure 4 evenly sprays the mold release agent onto the inner wall of the mold. After the car body 21 carrying the mold comes out from the other end of the spraying chamber 3, the cleaning and spraying of the mold are completed. The geared motor 54, diaphragm pump 42, second winch 26 and first winch 25 are shut down, and the mold is transferred to the next process with the help of an external gantry or other equipment. Then, control the second winch 26 to rotate in the reverse direction and the first winch 25 to rotate in the forward direction. The wire rope of the first winch 25 generates a traction force on the car body 21. Under the action of this traction force, the car body 21 moves along the travel track 1 to the initial position, and so on.

[0040] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
