Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a combined bracket for arranging vibrating rods during the building construction process. Background Art

[0002] In construction projects, concrete is a common building material. However, direct pouring of concrete after preparation at the construction site will lead to some defects, such as high porosity, low strength, uneven surface and poor durability. These defects will affect the quality and performance of concrete, which will directly affect the construction quality of the building. Therefore, during construction, concrete is usually treated by vibration and other methods to improve the density and strength of concrete and ensure the quality and service life of concrete. Vibrators are often used in this situation. Vibrators can compact concrete through vibration to remove bubbles in concrete and improve the density and strength of concrete, thereby greatly reducing the impact of the above defects on construction.

DETAILED DESCRIPTION

[0026] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] Example:

[0028] See also Figures 1 to 7, the utility model provides a technical solution:

[0029] A combined vibrator bracket includes a bracket 1, a rotating shaft fixing plate 2, a rotating shaft 3, a vibrating rod stabilizing rod 4, a connecting block 5, a clamping portion 6 and a transmission assembly 7. The rotating shaft fixing plate 2 is fixedly installed on one side of the bracket 1. The rotating shaft 3 is rotatably installed in the hole opened in the rotating shaft fixing plate 2 and can be rotated arbitrarily. One end of the vibrating rod stabilizing rod 4 is fixedly installed on the rotating shaft 3. The clamping portion 6 is hinged to the other end of the vibrating rod stabilizing rod 4 through the connecting block 5. The rotating shaft fixing plate 2 mainly functions to fix the rotating shaft 3. The rotating shaft 3 is a hollow shaft with the same length as the side of the bracket 1 and with plug-in interfaces at both ends. Figure 1 As shown, the main function is to connect the rotating shafts 3 on different brackets 1 together when the brackets 1 are spliced, so that the rotating shaft 3 can be rotated synchronously to drive the vibrating rod stabilizing rod 4 fixed to the rotating shaft 3 on the rotating shaft 3 and the connecting block 5 and the clamping part 6 at the front end of the stabilizing rod, so as to realize the synchronous adjustment of the rotation angle of the clamping part 6 of multiple brackets 1 and the depth of the vibrating rod inserted into the concrete as required.

[0030] The clamping part 6 includes a clamping shell 61, a clamping assembly and a driving assembly. The upper side of the clamping shell 61 is hinged to the connecting block 5. The two clamping assemblies are arranged opposite to each other and are movably installed at the front end of the clamping shell 61. Figure 3 As shown, the end of the clamping shell 61 facing the observer is the front end, wherein the clamping assembly forms a linear motion pair in the radial direction of the clamping shell 61, as shown in FIG. Figure 3 As shown, the left and right directions of the slots on the guide plate 64 are radial, the drive assembly is disposed in the clamping housing 61, and the power actuator of the drive assembly is in transmission connection with the two clamping assemblies, for driving the two clamping assemblies to move closer to or away from each other, so that the clamping portion can clamp or release the vibrator;

[0031] The power input end of the transmission assembly 7 is rotatably mounted on the bracket 1 , and the power output end thereof is connected to the driving assembly for driving the driving assembly to move.

[0032] As a preferred embodiment, the clamping assembly is composed of a clamping head 65, a spring 66 and a clamping plate 67. The end of the clamping head 65 close to the bracket 1 is an extension rod 651 end. The extension rod 651 is a part of the clamping head 65. The detailed structure is as follows: Figure 6As shown, the extension rod 651 is movably installed in the drive assembly, and a clamping plate 67 is installed on the inner side of the clamping head 65 through a spring 66. The function of the spring 66 is to clamp the vibrating rod in the middle of the clamping plate 67 in advance through its elastic force when clamping. As the clamping head 65 approaches, with the assistance of the spring 66, the clamping vibrator is more stable. When releasing, the clamping head 65 releases the vibrating rod, but the elastic potential energy possessed by the spring 66 when clamping does not release the vibrating rod immediately. Instead, the elastic potential energy of the spring 66 decreases as the distance between the clamping heads 65 increases, until the elastic potential energy of the spring 66 is less than the gravity exerted on the vibrating rod, and it will naturally slide down.

[0033] As a preferred embodiment, the clamping assembly is not limited to clamping by approaching the clamping plates, but can also be clamped by mechanical grippers and some other clamping methods.

[0034] As a preferred embodiment: the drive assembly includes a bevel gear I 62, an elliptical drive disk 63 and a guide plate 64, the elliptical drive disk 63 is rotatably installed in the clamping shell 61, the guide plate 64 is arranged on the end face of the clamping shell 61, the extension rod 651 of the clamping head 65 passes through the through groove on the guide plate 64, and the end of the extension rod 651 cooperates with the arc groove on the elliptical drive disk 63, the end face of the extension rod 651 is flush with the side face of the elliptical drive disk 63, and the side face of the elliptical drive disk 63 is fixedly mounted with a bevel gear I 62. The above-mentioned installation relationship between the elliptical drive disk 63 and the clamping shell 61 will be described in detail below. The overall shape of the elliptical drive disk 63 is elliptical, as shown in FIG. Figure 5 As shown, the rotating track for accommodating the elliptical drive disc 63 in the clamping housing 61 is circular as a whole. Figure 4 As shown, the supporting interaction mode between the two is that the length of the elliptical major axis is equal to the circle diameter, and the two rotate and interact in a circular orbit with the two end points of the elliptical major axis of the elliptical driving disk 63 as the motion interaction base points.

[0035] As a preferred embodiment: the transmission assembly 7 includes a bevel gear II 71, a universal joint coupling 72, a transmission chain 73 and a synchronous pulley 74. The bevel gear II 71 is rotatably installed in the clamping housing 61 through the mounting shaft and meshes with the bevel gear I 62. One end of the synchronous pulley 74 is rotatably installed in the through hole on the rear side of the bracket 1 through another mounting shaft. The two mounting shafts are each connected to the two ends of the transmission chain 73 through a universal joint coupling 72. When multiple brackets are combined together, a belt drive method can be adopted, that is, a synchronous belt is sleeved on multiple synchronous pulleys 74, and the last section of the synchronous belt is sleeved on the synchronous pulley for controlling the rotation of the belt to achieve synchronous control of the clamping and release of the clamping portion 6 of the combined bracket.

[0036] As a preferred embodiment, the transmission assembly is not limited to synchronous transmission control through synchronous pulleys, but can also be synchronous transmission control through sprockets and chains, as well as some other transmission control methods.

[0037] As a preferred embodiment: a central slot is provided on the vibrating rod stabilizing rod 4, and through holes are provided at the exact center of the clamping shell 61, the bevel gear I 62 and the elliptical drive disk 63. The central slot and these through holes can allow the vibrating rod and the soft shaft of the vibrator to pass through, so that after the vibration is completed, the clamping part can position the vibrating rod along the soft shaft and clamp it for recovery.

[0038] As a preferred embodiment: the bracket 1 is composed of a rectangular frame 11 and a fixing plate 12. A fixing plate 12 is provided between two parallel rectangular frames 11. One end of the rectangular frame 11 is provided with a plug interface and a pin hole on the side. The other end is provided with a plug rod and a pin hole is also provided on the side. Two adjacent brackets are spliced ​​through the plug interface on the rectangular frame and fixed through the pin hole. Figure 1 As shown, this bracket is only a sub-bracket of the spliced ​​combined bracket. When multiple areas need to be vibrated in different working conditions, multiple identical brackets can be combined from the plug interfaces at both ends of the rectangular frame 11 to expand the vibration area. Two support frames perpendicular to the ground can be erected on both sides of the required vibration position to support the combined bracket. In this way, the weight of this bracket will not affect the vibration process.

[0039] As a preferred embodiment: a motor fixing plate 8 is provided on the upper side of the bracket 1 for fixing the vibrating rod motor placed on the bracket. The vibrating instrument is generally divided into three parts: a vibrating motor as a source of vibrating power, a soft shaft for transmitting vibrating power, and a vibrator for outputting vibrating power. This part has not been fully introduced in the above, so the fixing method of the vibrating instrument on this bracket will be described in detail below. The vibrating motor is fixed on the motor fixing plate 8 provided on the upper side of the bracket 1, and the motor power output end is facing the direction of the clamping part 6, such as Figure 1 As shown, one end of the flexible shaft is fixedly connected to the power output end of the motor, and the two rotate synchronously. The flexible shaft passes through the middle slot on the vibrating rod stabilizing rod 4, and the other end of the flexible shaft is connected to the vibrator for vibrating concrete. The vibrator is a long cylinder in appearance. The middle part of the vibrator is clamped by the clamping head 65 of the clamping part 6. The end of the vibrator is connected to the flexible shaft and passes through the through hole opened in the center of the clamping shell 61, the bevel gear I 62 and the elliptical drive disk 63, so that the flexible shaft can easily transmit the power output of the motor while minimizing bending, thereby reducing the loss of transmitted power.

[0040] The operating principle of this utility model:

[0041] Before using this bracket, you need to install the vibrator on it, that is, install the vibrator motor on the motor fixing plate 8, and pass the power output flexible shaft of the vibrator through the middle slot on the vibrator rod stabilizing rod 4 and the through hole in the center of the clamping shell 61, bevel gear I 62 and elliptical drive disk 63, so as to facilitate the positioning of the vibrator rod along the flexible shaft after the vibration is completed and the recovery of the vibrator rod. Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, the synchronous pulley 74 on the rear side of the rotating bracket 1 transmits power through the transmission chain 73 to rotate the bevel gear II 71. As a result, due to the meshing between the bevel gear II 71 and the bevel gear I 62, and the bevel gear I 62 is fixedly connected to the elliptical drive disk 63, the elliptical drive disk 63 rotates. As the elliptical drive disk 63 rotates and is laterally limited by the guide plate 64 in the clamping shell 61, the extension rod 651 limited in its track drives the clamping head 65 to move away from each other to loosen, as shown in FIG. Figure 6 , after the vibrating rod is placed between the clamping plates 67 at one end of the clamping head 65, it can be inserted into the concrete and can be rotated after the clamping head 65 is loosened and naturally droops. The synchronous pulley 74 is then rotated, and the power is transmitted through the transmission chain 73, the bevel gear II 71 is engaged with the bevel gear I 62, the elliptical drive disc 63 is rotated and laterally limited by the guide plate 64, and the extension rod 651 that is limited in the track of the elliptical drive disc 63 and the guide plate 64 drives the clamping head 65 to do a clamping movement close to each other, controlling the clamping plate 67 and the clamping head 65 to clamp the vibrating rod in turn. Now, the vibration operation under different working conditions in the construction can be carried out, such as the working condition of a large site full of concrete that needs to be vibrated as much as possible without destroying the original distribution. Figure 1 As shown, multiple identical brackets in this article are sub-brackets. The number of horizontal rows of vibrating brackets is selected according to the vibrating length, and the number of vertical rows of vibrating brackets is selected according to the vibrating width. The brackets 1 are combined at the plug-in interfaces at both ends of the rectangular frame 11 to meet the requirements. Through the combined rotating shaft 3 and the synchronous pulley 74 with the synchronous belt, the worker standing outside the site can control the vibrating head in the combined bracket to insert into the concrete. The worker rotates the synchronous pulley 74 with the synchronous belt outside the site to synchronously control the entire row of vibrating brackets through the following steps: Figure 7 The transmission assembly 7 shown transmits the power transmitted from the synchronous upper transmission to the synchronous pulley 74, and receives the power from the transmission assembly through the driving assembly to drive the clamping head 65 to drive the clamping plate 67 to clamp and release the vibrating rod, and controls the depth of the clamped vibrating rod inserted into the concrete through the rotating shaft 3 connected to each other between the brackets, thereby realizing the off-site control of the following procedures: start of vibration, insertion of vibrating rod, release of vibrating rod, retraction of clamping part 6, vibration, end of vibration, positioning of vibrating rod along the flexible shaft, clamping of vibrating rod, lifting of clamping part 6, recovery of vibrating rod, completion of the operation, and thus completing the construction disassembly bracket.
