Description

TECHNICAL FIELD

[0001] The present application relates to the field of discharging equipment, in particular to a concrete discharging equipment for constructing a cable well. BACKGROUND

[0002] The prefabricated cable well is a standardized underground facility prefabricated in a factory, mainly used for cable laying, maintenance and protection, and has the characteristics of high strength, corrosion resistance and efficient construction. In the prior art, a core mold vibration forming process is usually used in the production of the prefabricated cable well, and the material is compacted by high-frequency vibration, and then demolding is performed. In order to ensure efficiency, multiple molds are arranged on the conveying device in the prior art, and the molds are moved by the conveying device. When the molds move to below the stock bin, the discharger is opened, and then the pre-configured concrete in the stock bin falls into the molds. When the mold cavity is filled, the conveying device can drive the mold to shift and then perform subsequent work. Due to the high adhesion of the concrete material itself, even if the discharger is closed in time after the mold moves out, a small amount of residual concrete will still drip from the discharge port. This part of concrete does not fall into the mold, but directly falls into the gap between the front and rear molds, or forms an attachment at the edge of the mold joint surface. The dripped concrete forms a hard block after air drying, which greatly increases the subsequent cleaning workload of the mold, and the concrete flowing into the joint gap of the mold makes the disassembly of the mold after work difficult. The hard block attached to the joint gap also makes the mold unable to closely fit subsequently. Due to different parameters of concrete in actual work, the discharge angle also needs to be adjusted accordingly. However, in the prior art, different types of dischargers need to be replaced when adjusting the discharge angle, which greatly slows down the production efficiency when producing different parameters of prefabricated parts. SUMMARY

[0003] In order to overcome the shortcomings of the prior art that the discharger will leave concrete, drip into the mold joint gap, cause a large cleaning workload of the mold, and make the mold unable to closely fit, and the prior art cannot adjust the discharge angle in time, the present application provides a concrete discharging equipment for constructing a cable well.

[0004] To achieve this purpose, the present application adopts the following technical solutions: A concrete discharging equipment for constructing a cable well, comprising a discharging assembly, the discharging assembly is provided with a flow guide slope, one end of the flow guide slope extends to a discharging end, and the discharging assembly is provided with a guide assembly. The guide assembly comprises a guide component, the guide component is rotationally connected to the lower end of the discharging end through a rotating shaft. The guiding component is divided into a first area and a second area by the rotating shaft. The first area is set at a first angle with the inclination direction of the guide slope, and the second area has an adjustment gap with the lower end face of the guide slope. An adjustment component is provided within the adjustment gap. One end of the adjustment component is movably connected to the guide component. The angle of the first adjustment angle is adjusted by adjusting the height of the adjustment component.

[0005] Compared with the prior art, the present invention has the following beneficial effects: By working together with the discharge assembly and the guiding components, the problem of concrete adhering to the discharge device and then dripping onto the mold, which leads to increased cleaning workload and the inability of the mold to fit tightly afterward, is avoided in the existing technology. By adjusting the component settings, the problem of needing to replace different models of ejectors when adjusting the discharge angle in existing technologies is avoided. This avoids the need to change ejectors when producing preforms with different parameters, which slows down production efficiency. Attached Figure Description

[0010] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0011] This invention provides a concrete discharge device for constructing cable wells.

[0012] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

[0013] A concrete discharge device for constructing cable wells, such as Figures 1-15As shown, it includes a discharge component 100, which is provided with a guide slope. One end of the guide slope extends to the discharge end b. The discharge component 100 is provided with a guide component 200. The guide assembly 200 includes a guide component 21, which is rotatably connected to the lower end of the discharge end b via a rotating shaft 24; The guide component 21 is divided by the pivot 24 and has a first region 21a and a second region 21b. The first region 21a is set at a first angle 21c with the inclination direction of the guide slope, and the second region 21b has an adjustment gap with the lower end face of the guide slope. An adjustment component 23 is provided within the adjustment gap. One end of the adjustment component 23 is movably connected to the guide component 200. The angle of the first included angle 21c is adjusted by adjusting the height of the adjustment component 23.

[0014] Before operation, connect the concrete silo outlet to the feeding end a of the discharge assembly 100. Then, install the device on the external guiding mobile equipment, and then the device will begin operation. When the pre-set mold is conveyed to the bottom of this device by the conveying device, the hopper outlet opens, and the concrete in the hopper flows through and into the flow cavity of the discharge assembly 100. Then it is discharged from the discharge end b of the discharge assembly 100 and enters the mold cavity. However, there are certain gaps between the molds. Although the outlet of the hopper closes after the mold cavity is full and the material has been transported away, the high viscosity of concrete causes some concrete to adhere to the guide slope of the discharge component 100 and then drip onto the mold. After the dripping concrete dries, it forms hard lumps, which greatly increases the workload of subsequent mold cleaning. In addition, the concrete flows into the mold's joints, making it difficult to disassemble the mold after it is completed. Furthermore, the hard lumps attached to the joints also prevent the mold from fitting tightly in the future. Therefore, this device is also equipped with a guiding assembly 200, which includes a guiding component 21. When concrete is discharged from the discharge end b, the flowing concrete impacts the guiding component 21. At this time, since the guiding component 21 is rotatably connected to the rotating shaft 24, as... Figure 3 As shown, the guide component 21 will rotate under force, at which point the guide component 21 will move from... Figure 1 The "standby mode" shown has changed to Figure 3 The "working state" shown indicates that the angle 21c formed by the first zone 21a and the guide slope of the discharge component 100 will change, thereby achieving the diversion of concrete at a preset angle. When the hopper outlet is closed, the guide component 21 loses its load and can then reset. At this time, the first included angle 21c returns to its initial angle. The residual concrete will adhere to the guide component 21, thus avoiding the problem of concrete adhering to the discharge device and dripping onto the mold, which would increase the cleaning workload and prevent the mold from fitting tightly in the future. Furthermore, in actual work, the discharge angle of concrete with different parameters also needs to be adjusted accordingly. If the angle is too small, the concrete will slide down intermittently like toothpaste being squeezed, and the coarse aggregate in the concrete is easy to get stuck at the discharge end, forming an arch bridge effect. If the angle is too large, the concrete will cause it to rush straight into the mold like a waterfall. However, the existing technology requires changing different models of discharge devices when adjusting the discharge angle. This means that the discharge device needs to be changed every time precast parts with different parameters are produced, which greatly slows down the production efficiency.

[0015] Therefore, the guide component 200 also includes an adjustment component 23. When it is necessary to discharge concrete with different parameters, the extension distance of the telescopic part of the adjustment component 23 can be adjusted by moving the locking mechanism of the adjustment component 23. After that, the locking mechanism of the adjustment component 23 is reset to achieve the telescopic positioning of the adjustment component 23. When the guide component 21 is rotated and tilted under force, the second zone 21b will tilt at a corresponding angle according to the unfolding distance of the adjusting component 23, and the corresponding first included angle 21c will change accordingly to adapt to the discharge angle of concrete with different parameters. This allows for rapid adjustment of the guide component 21, thus avoiding the problem of needing to replace different models of the ejector when adjusting the discharge angle in existing technologies. This would slow down production efficiency when changing the ejector when producing preforms with different parameters.

[0016] Example 2 Based on the above embodiment 1, as follows Figures 1-10 As shown, Preferably, the guide component 200 further includes a flow-blocking component 22; The flow-blocking component 22 includes a flow-blocking strip 221, which is disposed at one end of the discharge end b of the guide component 21; from the second direction y-view, the flow-blocking strip 221 protrudes from the guide component 21 to block dripping fluid.

[0017] Preferably, the discharge assembly 100 further includes a discharge component 11 and a first expansion component 14. A guide slope is provided on the discharge component 11, and both the feeding end a and the discharge end b are provided on the discharge component 11. The guide slope of the discharge component is provided with a first expansion component 14. The first expansion component 14 includes a slider 141, which is slidably connected to the guide slope and passes through the discharge component 11. The sliding member 141 is provided with an extension portion 1411, which is slidably connected to the discharge member 11 via an elastic member.

[0018] Preferably, the guide component 21 is provided with a mounting cover 211, which is connected to the flow-blocking component 22; The flow-blocking component 22 also includes at least two first limiting strips 223, a number of second limiting strips 224, and an elastic telescopic component 225; The flow barrier 221 is rotatably connected to the mounting cover 211 via a torsion spring, and there is a limiting gap between the flow barrier 221 and the guide component 21; The elastic telescopic member 225 is fixedly connected to the mounting cover 211. The elastic telescopic member 225 extends along the second direction y, and each end of the elastic telescopic member 225 is provided with at least one telescopic part, and the telescopic part can reciprocate and extend along the axial direction of the elastic telescopic member 225. The first limiting strip 223 has one end fixedly connected to the telescopic part of the elastic telescopic member 225, and the other end extends along the radial length direction of the telescopic part. It is provided with a limiting part 223a, which extends toward the flow blocking strip 221 and is located in the limiting gap. It also squeezes the flow blocking strip 221 so that the flow blocking strip 221 can protrude from the inclined surface of the guide member 21. The second limiting strip 224 is connected to the first limiting strip 223; The first expansion member 14 also includes a limiting bar 142, one end of which is connected to the sliding member 141, and the other end extends toward the guide member 211 and is provided with a limiting part; The mounting cover 211 is provided with a through groove 211a. When the mounting cover 211 is in working condition, the limiting bar 142 can pass through the through groove 211a to limit and compress the second limiting bar 224.

[0019] Preferably, the flow-blocking component 22 further includes a flexible protective sheet 222, which is fixedly connected to the flow-blocking strip 221 and connected to the guiding component 21.

[0020] Specifically, when the hopper outlet is closed, the guide component 21 loses its load and resets. At this point, the concrete impact stops, leaving a residual concrete film and suspended concrete liquid at the edge of the guide component 21. During the rotation and repositioning of the guide component 21, due to the liquid's inertia, viscosity, and adhesion to the slab surface, it is carried along by the movement of the guide component 21. When the concrete film peels and breaks, some liquid fails to completely detach from the guide component 21 and is carried along with the rotation of the guide component 21 to the position that becomes the lower surface after repositioning, thus forming the example droplet 001. Ultimately, it adheres to the surface in the form of droplets or liquid films, as shown in the example. Figure 15Even in this state, residual concrete will still adhere to the guide component 21 and subsequently drip onto the mold. Therefore, this device is provided with a flow-blocking component 22, which includes a flow-blocking strip 221. The flow-blocking strip 221 protrudes from the guide component 21. Thus, when the guide component 21 is reset, the flow-blocking strip 221 can further block the example droplet 001, so as to further prevent residual concrete from adhering to the guide component 21 and dripping into the mold. Furthermore, due to the high viscosity of concrete, when concrete flows in the existing discharge device, concrete aggregates often rub against each other to form intercepting blocks that get stuck in the discharge device. These intercepting blocks hinder the flow of concrete, making it impossible to fill the mold cavity in time, resulting in internal voids or surface gaps in the precast parts, thus reducing the yield rate of the products. Therefore, the discharge assembly 100 includes a discharge component 11 and a first expansion component 14. When concrete flows within the discharge component 11, if the concrete rubs against each other, it will compress the sliding component 141. At this time, the sliding component 141 will move under the force, so that when the concrete rubs against each other, it cannot stably press against the side wall of the internal space of the discharge component 11. This can prevent the concrete aggregate from rubbing against each other to form an intercepting block. At this time, the elastic element connected to the extension 1411 is subjected to force and generates a reset elastic force. When the rubbed concrete aggregate flows away normally, the elastic element releases the reset elastic force, which can drive the sliding element 141 to reset so that the sliding element 141 can perform subsequent work. Furthermore, although the flow-blocking strip 221 can block the example droplet 001, in actual operation, the flow-blocking strip 221 will affect the discharge angle of the concrete flowing from the guide component 21, which will affect the production of precast components to some extent. Therefore, the flow-blocking component 22 also includes a first limiting strip 223, a second limiting strip 224, and an elastic telescopic component 225. When the guide component 21 is in "standby mode", such as Figure 7 As shown, the flow barrier 221 is pressed against the limiting part 223a, so the flow barrier 221 can protrude from the guide member 21. When concrete impacts the guide component 21 and the guide component 21 is in "working state," the mounting cover 211 on the guide component 21 will cause all parts of the connected flow-blocking component 22 to rotate. At this time, the limiting bar 142 will pass through the through groove 211a and press against the second limiting bar 224, causing the limiting bar 142 to move under force. The force of the limiting bar 142 acts on the first limiting bar 223 at the corresponding position, thereby driving it to move. At this time, the movement of the first limiting bar 223 pulls the telescopic part of the corresponding connected elastic telescopic member 225 to unfold, and the telescopic part of the elastic telescopic member 225 generates a restoring elastic force. At this time, the limiting part 223a of the first limiting strip 223 disengages from the limiting gap and no longer squeezes and limits the flow-blocking strip 221. The flow-blocking strip 221 is rotatably connected to the mounting cover 211 via a torsion spring. Under the torsional force of the torsion spring, the flow-blocking strip 221 then... Figure 7 The "convex state" transforms into Figure 8 The "flat state" shown At this time, the guide component 21 is in the "working state," meaning the concrete flows over it. The flow-blocking strip 221 then does not obstruct the concrete. When the concrete hopper outlet is closed, the concrete no longer flows over the guide component 21, and the guide component 21 begins to reset. This reset causes the connected flow-blocking component 22 to rotate. At this point, the second limiting strip 224 loses the limiting pressure of the limiting lever 142, and the flow-blocking strip 221 returns to its "protruding state" to prevent the formation of the example droplet 001. In this way, the flow-blocking strip 221 will not affect the discharge angle of the concrete flowing through the guide component 21 when the guide component 21 is in the "working state"; Furthermore, the flow-blocking component 22 also includes a flexible protective sheet 222. The flow-blocking strip 221 and the guiding component 21 are connected to the flexible protective sheet 222. The flexible protective sheet 222 seals the installation gap between the flow-blocking strip 221 and the guiding component 21 to prevent concrete from flowing into the installation gap and affecting the normal operation of the flow-blocking strip 221 and the guiding component 21. Furthermore, since the flexible protective sheet 222 is made of a flexible and deformable material, the flexible protective sheet 222 will not affect the limiting part 223a's limiting of the flow-blocking strip 221.

[0021] Example 3 Based on the above embodiment 2, as Figures 6-15 As shown, Preferably, the discharge assembly 100 includes a second expansion component 13 and a limiting sleeve 12; The discharge component 11, extending along the first direction x, has at least two opposing movable slots. The movable slots are provided with second expansion members 13, and the second expansion members 13 completely cover the movable slots to block fluid from flowing out. The limiting sleeve 12 is set at the edge of the movable notch to constrain the movement distance of the second expansion component 13; The second expansion member 13 can move away from the discharge member 11 when it is squeezed by the fluid flow.

[0022] Preferably, the second expansion member 13 includes an elastically deformable piece 131 and a propulsion piece 132; An elastic deformation plate 131 is connected to the movable slot and completely covers the movable slot. A propulsion plate 132 is provided on the side of the elastic deformation plate 131 away from the flow cavity to constrain the deformation of the elastic deformation plate 131.

[0023] Preferably, the second expansion member 13 further includes an airbag 133; Airbag 133 is located on the side of the propulsion plate 132 opposite to the elastic deformation plate 131. Airbag 133 is equipped with a pressure monitor, which is connected in communication with a preset alarm device.

[0024] Preferably, the discharge assembly 100 further includes an opening and closing component 15; The opening and closing component 15 includes a drive component 151, which is fixedly connected to the discharge component 11. The working part of the drive component 151 is fixedly connected to a rotating cover 152. The drive component 151 is communicatively connected to the pressure monitor of the airbag 133.

[0025] Preferably, the second expansion member 13 further includes a pneumatic telescopic member 134; the pneumatic telescopic member 134 is connected to the airbag 133. When the airbag 133 is compressed, the gas inside it can drive the telescopic end of the pneumatic telescopic component 134 to unfold. The rotating shaft 24 is provided with a protrusion 24a, which extends radially along the rotating shaft 24 and is located on the side of the extension direction of the pneumatic telescopic member 134.

[0026] To further ensure that concrete aggregates do not rub against each other and form blockages, the discharge assembly 100 includes a second expansion member 13. When concrete rubs against each other, due to the arrangement of the second expansion member 13, the second expansion member 13 will move further on top of the movement of the first expansion member 14, thus further preventing concrete aggregates from rubbing against each other and forming blockages. Specifically, when the concrete particles rub against each other and exert force on the first expansion member 14, they will squeeze the elastic deformation plate 131. At this time, the elastic deformation plate 131 deforms under the force, preventing the concrete particles from laterally pressing against the discharge member 11 during friction. Furthermore, the elastic deformation plate 131 is constrained and pressed against by the propulsion plate 132, thus preventing unlimited deformation and avoiding the situation where the concrete is squeezed and punctured by the elastic deformation plate 131. Furthermore, when coarse aggregate concrete is discharged through the discharge port 11 at a large flow rate, although the device is equipped with a second expansion component 13 and a first expansion component 14, it is still difficult to avoid the situation where the intercepting block blocks the discharge port 11. Therefore, in order to enable the staff to quickly deal with the blockage of the discharge part 11, the second expansion component 13 also includes an airbag 133. When the push plate 132 is subjected to the concrete extrusion force transmitted by the elastic deformation plate 131, the push plate 132 will move under force. When the push plate 132 moves, it squeezes the airbag 133 at the corresponding position. At this time, the air pressure inside the airbag 133 changes. When the air pressure inside the airbag 133 reaches the alarm threshold, the pressure monitor set in the airbag 133 will send a signal to the preset alarm device, and the preset alarm device will remind the staff so that the staff can quickly and timely deal with the blockage of the discharge part 11. Furthermore, when blockage occurs inside the discharge component 11, existing technologies prevent the pressure on the inner wall of the discharge component 11 from continuing to increase by closing the concrete silo outlet. However, in actual operation, there is a distance between the concrete silo outlet and the discharge end b of the discharge component 11. This means that even when the concrete silo outlet is closed, A portion of concrete will still flow from the concrete silo outlet into the discharge port 11. When the discharge port 11 becomes clogged with concrete, this clogged concrete will continuously increase the pressure inside the discharge port 11. If the discharge end b of the discharge port 11 is open, the vibration caused when workers inspect the clogged discharge port 11 will pose a risk of concrete spraying out from the discharge end b and injuring workers. Therefore, the discharge assembly 100 also includes an opening and closing component 15. When the discharge component 11 is blocked, the opening and closing component 15 can block the discharge end b of the discharge component 11. Specifically, when the air pressure inside the airbag 133 reaches the alarm threshold, the pressure monitor installed in the airbag 133 will send a signal to the drive unit 151. At this time, the drive unit 151 starts to work, driving the connected rotating cover 152 to rotate the discharge end b. When the rotating cover 152 completely blocks the discharge end b, the drive unit 151 stops working, thus avoiding the problem of concrete spraying out from the discharge end b and injuring the workers. Furthermore, although the rotating cover 152 can seal the discharge end b, if the impact force of the concrete spraying is too large, the rotating cover 152 cannot tightly seal the discharge end b. Therefore, the rotating shaft 24 is provided with a protrusion 24a, and the second expansion component 13 is provided with a pneumatic telescopic component 134. When the airbag 133 is compressed, the gas inside it can drive the telescopic end of the pneumatic telescopic component 134 to expand. When the air pressure inside the airbag 133 reaches the alarm threshold, the pressure monitor installed in the airbag 133 first sends a signal to the drive component 151, so that the rotating cover 152 blocks the discharge end b. When the air pressure inside the airbag 133 reaches the alarm threshold, the telescopic end of the pneumatic telescopic component 134 unfolds, which pushes the protrusion 24a on the rotating shaft 24. When the protrusion 24a is subjected to force, it will start to drive the rotating shaft 24 to rotate, and the rotating shaft 24 will drive the connected guide component 21 to... Figure 15 In the state shown, the guide component 21 can push against the rotating cover 152, thereby achieving a tight seal between the rotating cover 152 and the discharge end b.
