Description

Technical Field

[0001] This utility model relates to the technical field of railway sleeper production equipment, and in particular to a concrete vibration table for easy fixing in railway sleeper production. Background Technology

[0002] In the railway sleeper production process, the concrete vibration table plays an irreplaceable role as a core process equipment. Its working principle is to generate high-frequency, low-amplitude mechanical vibration through the built-in vibration motor, which causes the concrete poured into the mold to produce a liquefaction effect. This vibration can effectively eliminate air bubbles generated inside the concrete during pouring, promote the rearrangement and tight interlocking of aggregate particles, and significantly improve the density of the concrete.

[0003] In the production of railway sleepers, sleeper molds come in various specifications and sizes. Existing concrete vibration tables mostly use positioning devices of a single specification. When changing to different specifications of molds, a lot of time is required to adjust the fixing parts to match the fixtures, which reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: In the process of railway sleeper production, there are various specifications and sizes of sleeper molds. Existing concrete vibration tables mostly use a single specification of positioning device. When changing molds of different specifications, a lot of time is required to adjust the fixing parts to adapt to the fixture, which reduces production efficiency. Therefore, a concrete vibration table for railway sleeper production that is easy to fix is ​​proposed.

A transverse screw is horizontally threaded into the second threaded hole. A second adjusting block is fixedly installed at one end of the transverse screw. A second mounting block is rotatably installed at the end of the transverse screw away from the second adjusting block. A second positioning plate is slidably installed on the side of the second mounting block through a second sliding component. The first positioning plate and the second positioning plate are vertically arranged.

[0009] Preferably, the first mounting block has a first T-shaped groove on the side near the right-angle positioning plate, and the first sliding assembly includes a first slide rail that slides horizontally in the first T-shaped groove and two first stops that are symmetrically fixed at both ends of the first slide rail.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6 A concrete vibrating table for easy fixing in railway sleeper production includes a vibrating platform 1, a right-angle positioning plate 2 fixedly installed on the upper surface of the vibrating platform 1, a first fixing seat 3 fixedly installed on the upper surface of the vibrating platform 1, a first threaded hole on the first fixing seat 3, a longitudinal screw 4 horizontally threaded into the first threaded hole, a first adjusting block 5 fixedly installed at one end of the longitudinal screw 4, a first mounting block 6 rotatably installed at the end of the longitudinal screw 4 away from the first adjusting block 5, and a first positioning plate 7 slidably installed on the side of the first mounting block 6 through a first sliding component. The vibrating platform 1 has a built-in vibrating motor that can generate high-frequency, low-amplitude mechanical vibration. When the mold is placed on the vibrating platform 1, it can drive the mold to vibrate together, which can effectively eliminate air bubbles generated inside the concrete during pouring.

[0026] A second fixed seat 8 is fixedly installed on the upper surface of the vibration platform 1. A second threaded hole is opened on the second fixed seat 8. A transverse screw 9 is inserted into the second threaded hole with a horizontal thread. A second adjusting block 10 is fixedly installed at one end of the transverse screw 9. A second mounting block 11 is rotatably installed at the end of the transverse screw 9 away from the second adjusting block 10. A second positioning plate 12 is slidably installed on the side of the second mounting block 11 through a second sliding component. The first positioning plate 7 and the second positioning plate 12 are vertically arranged.

[0027] When changing molds of different specifications, place the mold on the vibration platform 1, and make one corner of the mold contact the right-angle positioning plate 2. Then rotate the longitudinal screw 4. Under the action of the first fixed seat 3, the first positioning plate 7 is moved towards the mold and contacts the side of the mold. Then rotate the transverse screw 9. Under the action of the second fixed seat 8, the second positioning plate 12 is moved towards the mold and contacts the side of the mold. The right-angle positioning plate 2, the first positioning plate 7, and the second positioning plate 12 clamp and fix the mold from three directions. This allows for quick and easy clamping and fixing of sleeper molds of different specifications and sizes between the first positioning plate 7, the second positioning plate 12, and the right-angle positioning plate 2. The operation is convenient, time-saving, labor-saving, and effectively improves production efficiency.

[0028] The first mounting block 6 has a first T-shaped groove on the side near the right-angle positioning plate 2. The first sliding component includes a first slide rail 13 that slides horizontally in the first T-shaped groove and two first stops 14 that are symmetrically fixed at both ends of the first slide rail 13. The first positioning plate 7 is fixedly connected to the first slide rail 13. The first slide rail 13 can move horizontally on the first mounting block 6 through the first T-shaped groove, thereby driving the first positioning plate 7 to move horizontally on the first mounting block 6. Adjusting the horizontal position of the first positioning plate 7 on the vibration platform 1 makes the first positioning plate 7 fully contact the side of the mold, thereby improving the stability of the mold clamping.

[0029] The second mounting block 11 has a second T-shaped groove on the side near the right-angle positioning plate 2. The second sliding assembly includes a second slide rail 15 that slides horizontally in the second T-shaped groove and two second stops 16 that are symmetrically fixed at both ends of the second slide rail 15. The second positioning plate 12 is fixedly connected to the second slide rail 15. The second slide rail 15 can move horizontally on the second mounting block 11 through the second T-shaped groove, thereby driving the second positioning plate 12 to move horizontally on the second mounting block 11. Adjusting the horizontal position of the second positioning plate 12 on the vibration platform 1, so that the second positioning plate 12 fully contacts the side of the mold, thereby improving the stability of the mold clamping.

[0030] Both the longitudinal screw 4 and the transverse screw 9 are threaded with positioning nuts 17. The two positioning nuts 17 are in contact with the first fixed seat 3 and the second fixed seat 8, respectively. When the first positioning plate 7 and the second positioning plate 12 are in contact with the mold, the positioning nuts 17 can be rotated to make the positioning nuts 17 contact the side of the first fixed seat 3 or the second fixed seat 8. The positioning nuts 17 can lock the longitudinal screw 4 and the transverse screw 9, preventing the longitudinal screw 4 and the transverse screw 9 from loosening during vibration, and further improving the stability of the first positioning plate 7 and the second positioning plate 12 in clamping the mold.

[0031] Rectangular columns 18 are symmetrically fixedly installed on the lower surfaces of the first positioning plate 7 and the second positioning plate 12. Roller balls 19 are rolled and embedded at the lower ends of the rectangular columns 18. The roller balls 19 roll and contact the surface of the vibration platform 1. When the first positioning plate 7 and the second positioning plate 12 move horizontally, the rectangular columns 18 and the roller balls 19 can play a supporting role. The roller balls 19 roll relative to the upper surface of the vibration platform 1. With the support of the rectangular columns 18 and the roller balls 19, the horizontal movement of the first positioning plate 7 and the second positioning plate 12 can be guaranteed.

[0032] An L-shaped support column 20 is fixedly installed on the vibration platform 1. A third threaded hole is opened on the support column 20, and an adjusting bolt 21 is vertically threaded into the third threaded hole. A limit plate 22 is rotatably installed on the lower end of the adjusting bolt 21. When the mold is clamped on the right-angle positioning plate 2, the first positioning plate 7 and the second positioning plate 12, the adjusting bolt 21 is rotated by a wrench. Under the action of the third screw, the adjusting bolt 21 drives the limit plate 22 to move vertically downward, so that the limit plate 22 contacts the upper end of the mold, applies pressure to the upper end of the mold, and ensures that the bottom of the mold is in full contact with the upper surface of the vibration platform 1, thus ensuring the vibration effect of the vibration platform 1 on the mold.

[0033] In this invention, when changing molds of different specifications, the mold is placed on the vibration platform 1, and one corner of the mold is brought into contact with the right-angle positioning plate 2. Then, the longitudinal screw 4 is rotated, and under the action of the first fixed seat 3, the first positioning plate 7 is moved towards the mold and comes into contact with the side of the mold. Then, the transverse screw 9 is rotated, and under the action of the second fixed seat 8, the second positioning plate 12 is moved towards the mold and comes into contact with the side of the mold. The right-angle positioning plate 2, the first positioning plate 7, and the second positioning plate 12 clamp and fix the mold from three directions, so that sleeper molds of different specifications and sizes can be quickly and easily clamped and fixed between the first positioning plate 7, the second positioning plate 12, and the right-angle positioning plate 2. The operation is convenient, time-saving, labor-saving, and effectively improves production efficiency.
