Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 3: the embodiment discloses a roughening device for a concrete prefabricated member, which comprises two bottom beams 1, an end cross beam 2, a middle cross beam 3 and a roughening cutter assembly, wherein the end cross beam 2, the middle cross beam 3 and the roughening cutter assembly are connected between the two bottom beams 1, and each bottom beam 1 is at least provided with two rollers 11 for connecting a ground rail; the napping knife assembly comprises a rotating shaft 4, a rotating shaft connecting rod 5 and a napping knife connecting rod 6, wherein two ends of the rotating shaft 4 are respectively rotatably connected to two bottom beams 1, two ends of the rotating shaft connecting rod 5 are respectively connected with the rotating shaft 4 and the napping knife connecting rod 6, a plurality of napping knives 7 and spacer bushes 71 are arranged on the napping knife connecting rod 6, the napping knives 7 and the spacer bushes 71 are arranged alternately, the rotating shaft connecting rod 5 is at least two, and the napping knife assembly is further connected with a height adjusting device used for driving the napping knife connecting rod 6 to lift. The napping knife 7 and the spacer 71 are freely threaded on the napping knife connecting rod 6, and can freely slide on the napping knife connecting rod 6 in actual use, so that the napping knife can act on different working positions (because concrete prefabricated parts needing napping are not always arranged between two ground rails).
Specifically, the height adjusting device comprises a screw 8, a screw support 32 and a nut 9, wherein the screw support 32 and the nut 9 are connected to the screw 8, the screw support 32 is hinged to the middle cross beam 3, the nut 9 is hinged to the napping knife assembly, and the end part of the screw 8 is further connected with a driving device for driving the screw 8 to rotate. The drive means is preferably a handwheel 81.
Specifically, as shown in fig. 3: the side of the screw 8 is provided with an annular bulge 801, and an end face bearing 321 sleeved on the screw 8 is arranged between the annular bulge 801 and the screw support 32. The annular projection 801 acts as a shoulder for supporting the screw 8 via the end face bearing 321.
The screw 8 is preferably a trapezoidal thread or a rectangular thread, because the trapezoidal thread or the rectangular thread has better service life and transmission efficiency, and is more suitable for the use scene of the embodiment.
Specifically, the number of the rotating shaft connecting rods 5 is three, the three rotating shaft connecting rods 5 are arranged at equal intervals, the nuts 9 are hinged to the rotating shaft connecting rods 5 in the middle, and auxiliary connecting rods 51 connected to the rotating shaft connecting rods 5 are further arranged between the napping knife connecting rods 6 and the rotating shaft 4. The auxiliary connecting rod 51 plays a role in reinforcing the strength and rigidity of the napping knife assembly.
Specifically, two ends of the rotating shaft 4 are connected to the upper surface of the bottom beam 1 through the support 41, and a bearing is further arranged between the rotating shaft 4 and the support 41. The support 41 is one of the more common parts of the prior art and is available by direct purchase.
As shown in fig. 1: the length of the broach connecting rod 6 is greater than the distance between the inner sides of the two bottom beams 1. Like this, the both ends of broach connecting rod 6 can contact with the upper surface of two floorbar 1, play spacing effect, avoid broach connecting rod 6 to move down and contact for the concrete prefabricated part.
The two ends of the end cross beam 2 are connected to the bottom beam 1 by vertically arranged end cross beam extensions 21. The end cross beam extension section 21 of vertical setting can play the effect that increases the height of end cross beam 2, when this embodiment does not dispose the walking motor, is convenient for artifically promote whole napping device to walk on the ground rail through end cross beam 2.
The roller 11 is also connected with the power output end of the motor 12. The motor 12 is a walking motor, which belongs to an optional device in the embodiment, because if the motor 12 is configured and the motor 12 is an alternating current motor, the whole napping device needs to be configured with a more complicated wire connecting power supply (because the napping device walks in operation); if the motor 12 is a dc motor, a battery is required, which also increases the cost and the mass of the entire device. The motor 12 can be configured as desired in a practical application.
The during operation is placed gyro wheel 11 on the ground rail, and the frictional force between gyro wheel 11 and the ground rail is less, the utility model discloses a dead weight is also less, consequently in practical application, manual implementation is not hard, and the activity is free, convenient reciprocating sliding.
The screw 8 is rotated through the hand wheel 81, the screw 8 is matched with the nut 9 to adjust the angle of the rotating shaft connecting rod 5 relative to the ground, and on the premise that the thickness of the concrete prefabricated part is fixed, when the angle is larger, the distance between the galling cutter connecting rod 6 and the concrete prefabricated part is larger, the distance between the galling cutter 7 and the concrete prefabricated part is larger, and the acting force of the galling cutter 7 on the concrete prefabricated part is smaller or zero; on the contrary, when the angle of the rotating shaft connecting rod 5 relative to the ground is smaller, the acting force of the galling knife 7 on the concrete prefabricated member is larger. On the other hand, through adjusting screw 8, also can satisfy the concrete prefabricated member user demand of different thickness. In the process of rotating the screw 8, the screw support 32 and the nut 9 are always perpendicular to the screw 8, so that the requirements of the screw 8 and angle change can be met.
The utility model discloses simple structure, quality are less, can utilize the ground rail among the prior art, can directly operate whole device through the mode of carrying out in the in-service use, through the distance between the adjustable napping sword 7 of rotatory screw rod 8 and the concrete prefab for adjust the napping degree of depth and can satisfy the napping demand of not co-altitude concrete prefab. The napping knife 7 and the spacer 71 are freely threaded on the napping knife connecting rod 6, and can freely slide on the napping knife connecting rod 6 in actual use, so that the napping knife 7 and the spacer 71 act on different working positions. Compared with large-scale napping equipment in the prior art, the utility model has the advantages of low cost, low use cost and flexible operation.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
