Description

Technical Field

[0001] The invention relates to the technical field of cement pouring devices, in particular to a cement pouring device used for cement pole production. Background Art

[0002] Concrete (cement) poles are divided into ordinary reinforced concrete poles and prestressed concrete poles. The cross-section of the poles is square, octagonal, I-shaped, circular or other special-shaped sections. The most commonly used are circular sections and square sections. The length of the pole is generally 4.5 to 15 meters. There are two types of circular poles: conical poles and equal-diameter poles. The tip diameter of the conical pole is generally 100 to 230 mm, and the taper is 1:75; the diameter of the equal-diameter pole is 300 to 550 mm; the wall thickness of both is 30 to 60 mm. In the 1980s, China developed centrifugal circular prestressed concrete poles. Its manufacturing process is mainly to longitudinally tension the steel wire skeleton in the steel mold, and then squeeze out the excess water from the concrete under the action of centrifugal force, thereby greatly improving the compactness and strength of the concrete. In order to enable the concrete to reach more than 70% of the design strength more quickly, steam curing can be carried out to shorten the demoulding cycle. The use of prestressed concrete poles saves steel than ordinary reinforced concrete poles, and can also improve crack resistance and service life. Electric poles are bridges of electricity, allowing electricity to be transported to various places. Cement poles are made of concrete and steel bars or steel wires. Cement poles are prestressed or non-prestressed. The manufacture of cement poles requires the use of cement pouring equipment to pour cement into prepared molds. After centrifugal rotation and high-temperature heating, the cement poles can be formed.

[0003] During the cement pouring process of cement poles, the pouring equipment pours cement into the lower mold of the cement pole. After pouring into the lower mold, the workers gather the cement mortar poured into the lower mold by hand, and make the upper part of the cement mortar roughly circular, so that it is convenient to assemble the upper mold on the lower mold, so that the upper mold and the lower mold form a cylindrical mold, and the workers gather the cement mortar to avoid the phenomenon that part of the cement mortar does not enter the upper mold and the lower mold when the upper mold is assembled on the lower mold. Due to the long length of the cement pole, it takes a long time for the workers to gather the cement mortar, which makes the operation more inconvenient and results in low work efficiency.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 - Figure 8The present invention provides a technical solution: a cement pouring device for cement pole production, comprising a feeding bin 4 installed on an external pouring device, the feeding bin 4 is driven to move horizontally by a translation mechanism on the pouring device, a feeding port 3 is arranged on the periphery of the upper side of the feeding bin 4, the feeding port 3 is connected to an external cement mortar conveying system through a pipeline, the cement mortar conveying system conveys cement mortar into the feeding bin 4 through the feeding port 3, and the top of the feeding bin 4 is open and a bin cover 2 is screwed, a motor 1 is vertically installed on the top of the bin cover 2, the output shaft of the motor 1 is driven and connected to a drive shaft 13, and the drive shaft The part 13 that penetrates into the feeding bin 4 is equipped with a spiral conveying piece 12. The maximum outer diameter of the periphery of the spiral conveying piece 12 matches the inner diameter of the feeding bin 4 and is in a sliding contact state. When the cement mortar is transported into the feeding bin 4, the motor 1 is started, and the output shaft of the motor 1 rotates and drives the driving shaft 13 to rotate, so that the driving shaft 13 drives the spiral conveying piece 12 to rotate. When the spiral conveying piece 12 rotates, it will generate shear force on the cement mortar in the feeding bin 4, which will have a stirring effect on the cement mortar on the one hand, and drive the cement mortar to be transported toward the lower side opening of the feeding bin 4 on the other hand;

[0035] The lower end of the feeding bin 4 is connected with a transition bin 5, and the outer diameter of the transition bin 5 decreases from top to bottom in a bundle shape. The end with the largest outer diameter of the transition bin 5 is connected to the feeding bin 4. In addition, a feeding pipe 15 is fixedly connected to the lower end of the transition bin 5. The lower mold of the external cement pole is located below the feeding pipe 15, and the length direction is consistent with the linear motion direction of the feeding bin 4. The outer diameter of the feeding pipe 15 matches the minimum outer diameter of the transition bin 5. The peripheral edge of the feeding pipe 15 is sleeved with a sliding sleeve 22 that can slide freely up and down. The material of the sliding sleeve 22 can be stainless steel, or the surface of the sliding sleeve 22 can be chrome-plated to reduce the friction of the sliding sleeve 22 sliding on the peripheral edge of the feeding pipe 15. In addition, a mounting cavity in the form of a blind hole is provided at the bottom of the sliding sleeve 22, and a flange made of outward-turned is provided at the lower end of the feeding pipe 15. The flange is engaged in the mounting cavity and can slide freely up and down, so that the flange has a limiting effect on the sliding sleeve 22 sliding downward on the feeding pipe 15;

[0036] Two fixed arms 6 are fixedly connected to the periphery of the sliding sleeve 22, and a fixed sleeve 19 is fixedly connected to the lower surface of the fixed arm 6. In addition, the fixed arm 6 is symmetrically arranged along the axial direction of the sliding sleeve 22. A rotating shaft 17 is coaxially penetrated on the fixed sleeve 19. The rotating shaft 17 can slide freely along the axial direction of the fixed sleeve 19 on the fixed sleeve 19. At the same time, the rotating shaft 17 can also rotate freely around its own axial direction on the fixed sleeve 19. A connecting column is fixedly connected to one end of the rotating shaft 17, and a gathering plate 7 is fixedly connected to the lower end of the connecting column. The two gathering plates 7 are symmetrically arranged along the axis of the feeding tube 15. The gathering plates 7 are arc-shaped, and the inner arc surface of the gathering plates 7 faces the feeding tube 15. The mounting arm 8 on the lower surface of the fixed arm 6 is rotatably connected to the roller 9 at the lower end of the mounting arm 8. Two strip plates 11 are arranged below the feeding bin 4. The two strip plates 11 are mounted on the centrifugal mechanism of the external irrigation equipment. In addition, the strip plates 11 are provided with a plurality of roller grooves 10 in the form of notches at equal intervals along the length direction thereof. When the feeding bin 4 moves horizontally, the roller 9 will roll alternately on the upper surface of the strip plate 11 and in the roller groove 10. When the roller 9 rolls from the upper surface of the strip plate 11 to the roller groove 10, the mounting arm 8 will move downward, thereby causing the sliding sleeve 22 to move downward. In addition, the periphery of the feeding pipe 15 A stop ring 14 is fixedly sleeved, and the stop ring 14 is located above the sliding sleeve 22. A heavy-load spring 16 is sleeved on the feeding tube 15. The two ends of the heavy-load spring 16 elastically press against the stop ring 14 and the sliding sleeve 22 respectively. The heavy-load spring 16 generates a downward elastic pressing force on the sliding sleeve 22, so that the sliding sleeve 22 moves downward, and then the gathering plate 7 moves downward. The external cement pole lower mold is located between the two gathering plates 7. When the gathering plate 7 moves downward, it will generate an extrusion force on the cement mortar in the inner cavity of the external lower mold, so that the cement mortar slides along the inner arc surface of the gathering plate 7, and makes The gathering plate 7 has a gathering effect on the cement mortar. Conversely, when the roller 9 rolls from the roller groove 10 to the upper surface of the strip plate 11, the roller 9 will drive the mounting arm 8 to move upward, and the sliding sleeve 22 will move upward, thereby causing the gathering plate 7 to move upward. When the roller 9 rolls from the upper surface of the strip plate 11 to the roller groove 10 again, the gathering plate 7 will move downward again and have a gathering effect on the cement mortar. In addition, during the two adjacent gathering processes of the gathering plates 7, the two gathering plates 7 have repeated gathering areas, that is, the gathering areas of the gathering plates 7 for the cement mortar are continuous and will not be interrupted.

[0037] In addition, one end of the rotating shaft 17 away from the fixed arm 6 is fixedly sleeved with a limit ring 20, and a return spring 21 is sleeved around the rotating shaft 17. The two ends of the return spring 21 in the elastic direction elastically press against the limit ring 20 and the fixed sleeve 19 respectively. A sliding pin 18 is horizontally penetrated by the periphery of the fixed sleeve 19. A special-shaped groove for the sliding pin 18 to be inserted is opened on the periphery of the rotating shaft 17. The special-shaped groove includes a first spiral groove 23, a straight groove 24 and a second spiral groove 25 connected end to end along the length direction of the rotating shaft 17 (or in the direction away from the connecting column). The spiral directions of the first spiral groove 23 and the second spiral groove 25 are opposite. When the end of the sliding pin 18 moves from the first During the process of sliding from the spiral groove 23 to the straight groove 24, the rotating shaft 17 will rotate a certain angle, thereby causing the rotating shaft 17 to drive the connecting column and the gathering plate 7 to rotate toward the inner side of the feeding pipe 15. When the end of the sliding pin 18 slides from the straight groove 24 to the second spiral groove 25, the rotating shaft 17 will rotate in the opposite direction, thereby driving the gathering plate 7 to swing in the opposite direction, so that the gathering plate 7 swings toward the outer side of the feeding pipe 15. In addition, the end of the sliding pin 18 that is inserted into the fixed sleeve 19 is set in a ball head shape, so that the sliding resistance of the end of the sliding pin 18 when sliding in the first spiral groove 23, the straight groove 24 and the second spiral groove 25 is small.

[0038] The working principle of the present invention is as follows: when the external cement conveying system conveys the cement mortar to the feed port 3, the cement mortar will enter the feeding bin 4, and at the same time, the motor 1 is started, the output shaft of the motor 1 rotates, and the driving shaft 13 drives the spiral conveying piece 12 to rotate. When the spiral conveying piece 12 rotates, a shear force will be generated on the cement mortar in the feeding bin 4, which will have a stirring effect on the cement mortar on the one hand, and on the other hand, the cement mortar will be driven to be conveyed toward the lower side of the feeding bin 4, so that the cement mortar enters the transition bin 5. Since the inner diameter of the transition bin 5 decreases from top to bottom, the fluidity of the cement mortar entering the transition bin 5 is reduced, so that the cement mortars are squeezed against each other, and the larger bubbles in the cement mortar are discharged;

[0039] The external translation mechanism drives the feeding bin 4 to move horizontally at a slow speed, so that the cement mortar falls from the feeding pipe 15 into the inner cavity of the external lower mold. With the horizontal movement of the feeding bin 4, the roller 9 rolls alternately on the upper surface of the strip plate 11 and the roller groove 10. When the roller 9 rolls from the upper surface of the strip plate 11 to the roller groove 10, the mounting arm 8 will move downward, so that the sliding sleeve 22 moves downward. In addition, a stop ring 14 is fixedly sleeved on the periphery of the feeding pipe 15. The stop ring 14 is located above the sliding sleeve 22. A heavy-loaded spring 16 is sleeved on the feeding pipe 15. The two ends of the heavy-loaded spring 16 in the elastic direction elastically resist the stop ring 14 and the sliding sleeve 22 respectively. The heavy-loaded spring 16 generates a downward elastic resisting force on the sliding sleeve 22, so that the sliding sleeve 22 is downward, and the gathering plate 7 moves, so that the gathering The gathering plate 7 moves downward, and in the process of downward movement, the gathering plate 7 generates an extrusion force on the cement mortar in the inner cavity of the external lower mold (the specific principle will be explained later), so that the cement mortar slides along the inner arc surface of the gathering plate 7 to produce a gathering effect on the cement mortar. On the contrary, when the roller 9 rolls from the roller groove 10 to the upper surface of the strip plate 11, the roller 9 will drive the mounting arm 8 to move upward, and the sliding sleeve 22 will move upward, so that the gathering plate 7 moves upward. When the roller 9 rolls from the upper surface of the strip plate 11 to the roller groove 10 again, the gathering plate 7 will move downward again and produce a gathering effect on the cement mortar. In addition, in the two adjacent gathering processes of the gathering plates 7, the two gathering plates 7 have repeated gathering areas, that is, the gathering area of ​​the gathering plates 7 for the cement mortar is continuous and will not be interrupted.

[0040] When the gathering plate 7 gathers the cement mortar, the surface of the cement mortar and the inner arc surface of the gathering plate 7 have a large friction force, so that the friction resistance between the gathering plate 7 and the cement mortar is greater than the elastic resisting force of the return spring 21, so that the gathering plate 7 is in a static state relative to the cement mortar in the axial direction of the rotating shaft 17. At this time, the gathering plate 7 and the rotating shaft 17 will be in a relatively static state relative to the strip plate 11 or the cement mortar, and the fixed sleeve 19 will slide on the surface of the rotating shaft 17, and the limit ring 20 will compress the return spring 21. The return spring 21 accumulates elastic potential energy, and the fixed sleeve 19 will move horizontally along the length direction of the strip plate 11. During the horizontal movement, the end of the sliding pin 18 will slide from the first spiral groove 23 to the straight groove 24. During this process, the rotating shaft 17 will rotate a certain angle (the rotation angle is an acute angle), so that the rotating shaft 17 drives the connecting column and the gathering plate 7 to rotate toward the inner side of the feeding pipe 15, so that the gathering plate 7 has a gathering effect on the cement mortar;

[0041] When the end of the sliding pin 18 slides from the straight groove 24 to the second spiral groove 25, the rotating shaft 17 will rotate in the opposite direction, thereby driving the gathering plate 7 to swing in the opposite direction, so that the gathering plate 7 swings toward the outside of the feeding pipe 15, so that after the cement mortar is gathered, the gathering plate 7 can be reset, thereby preventing the gathering plate 7 from interfering with the cement mortar being poured when the rotating shaft 17 is subsequently reset in horizontal movement. In addition, the end of the sliding pin 18 that is inserted into the fixed sleeve 19 is arranged in a ball head shape, so that the sliding resistance of the end of the sliding pin 18 when sliding in the first spiral groove 23, the straight groove 24 and the second spiral groove 25 is small.
