Description

Technical Field

[0001] The present application relates to the technical field of concrete plate vibrators, in particular to a concrete vibrating plate. Background Art

[0002] A concrete vibrating plate is a device that uses an electric motor to generate vibration. It is mainly used for concrete compaction in construction projects. The vibrating plate mainly consists of three parts: an electric motor, a flexible shaft combination, and a vibrating rod. The electric motor drives the eccentric block to rotate to generate centrifugal force and form vibration.

[0003] When the motor rotates, it drives the eccentric block to rotate at high speed around the central axis, generating centrifugal force, thereby causing the entire equipment to vibrate, and transmitting this vibration to the concrete mixture. However, since the length of the vibrating plate in the prior art is fixed, when working on a wider road surface, the operator needs to reciprocate multiple times to complete the road leveling work, which not only increases the labor intensity of the operator, but also reduces the efficiency of construction. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a concrete vibrating plate, which has the advantages of facilitating the increase of the vibration area and solves the problem of the small vibration area.

[0005] To achieve the above-mentioned object, the present application provides the following technical solution: a concrete vibrating plate, comprising a plate vibrator, wherein the plate vibrator comprises a vibrating plate and a vibration driving end, wherein the vibration driving end is fixed to the top of the vibrating plate, and connecting blocks are fixed to the left and right ends of the top of the vibrating plate, and the left and right ends of the vibrating plate are provided with extension structures;

[0006] The extension structure includes two extended vibration plates, two positioning blocks, a plug-in block fixedly installed on the opposite wall of the two extended vibration plates, a pressing structure fixedly installed on the top of the two positioning blocks, and a resistance structure fixedly installed on the top of the two positioning blocks.

[0007] The above technical solution can increase the vibration area of ​​the vibrating plate, reduce the number of round trips when constructing a wider road surface, reduce the labor intensity of operators, improve construction efficiency, and improve the performance of the plate vibrator.

[0008] Furthermore, grooves for receiving plug-in blocks are provided at both left and right ends of the vibration plate, and the plug-in blocks are plugged into the grooves. Positioning grooves for receiving positioning blocks are provided at the top ends of the two plug-in blocks.

[0009] By adopting the above technical solution, the extended vibration plate can be spliced ​​together with the regular vibration plate through the plug-in block, and the positioning block is plugged into the positioning groove of the plug-in block, so that the plug-in block can be fixed in the groove, so that the extended vibration plate can be installed and fixed together with the vibration plate.

[0010] Furthermore, the bottom walls of the two connecting blocks are provided with through holes for the positioning blocks to pass through, and the left and right ends of the top of the vibration plate are provided with connecting holes, the through holes correspond to the connecting holes, and the positioning blocks are slidably connected to the inner sides of the through holes and the connecting holes.

[0011] By adopting the above technical solution, the positioning block can be moved out of the connecting block and moved into the groove of the vibration plate, which facilitates the positioning block to move into the positioning groove of the plug-in block.

[0012] Furthermore, the pressing structure includes two vertical blocks, two groups of vertical plates, horizontal bars fixedly installed at the left and right ends of the vertical blocks, and connecting plates fixedly installed at the front ends of the two vertical plates on the same side. The front ends of the connecting plates are rotatably connected to screws through bearings.

[0013] The above technical solution is adopted to drive the positioning block to move up and down, and to fix the positioning block in the groove or the connecting block.

[0015] By adopting the above technical solution, when the cross bar moves to the lower end of the pressing slot, the cross bar can push the positioning block downward through the vertical block. Conversely, when the cross bar moves to the top of the pressing slot, the cross bar can pull the positioning block upward through the vertical block and can limit the movement range of the cross bar.

[0016] Furthermore, the front ends of the two connecting blocks are each provided with a threaded hole for allowing a screw to pass through the interior thereof, and the width of the positioning block is smaller than the distance between the left and right vertical plates of the same group.

[0017] By adopting the above technical solution, the screw rod can drive the connecting plate to move back and forth in the connecting block, so as to prevent the two vertical plates in the same group from blocking the longitudinal movement of the positioning block.

It can also be used for construction on narrow road surfaces, which can increase the scope of use. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] See also Figure 1The concrete vibration plate in this embodiment includes a plate vibrator, which includes a vibration plate 1 and a vibration driving end 2. The vibration driving end 2 is fixed to the top of the vibration plate 1. Connecting blocks 3 are fixed to the left and right ends of the top of the vibration plate 1. Extension structures are provided at the left and right ends of the vibration plate 1.

[0031] See also Figures 1 to 4 The extension structure in this embodiment includes two extended vibration plates 4, two positioning blocks 42, a plug-in block 41 fixedly installed on the opposite wall of the two extended vibration plates 4, a pressing structure fixedly installed on the top of the two positioning blocks 42, and a resistance structure fixedly installed on the top of the two positioning blocks 42.

[0032] Among them, the left and right ends of the vibration plate 1 are provided with grooves 411 for the plug-in blocks 41 to be located therein, and the plug-in blocks 41 are plugged into the inside of the grooves 411, so that the extended vibration plate 4 can be spliced ​​together with the regular vibration plate 1 through the plug-in blocks 41, and the tops of the two plug-in blocks 41 are provided with positioning grooves for the positioning blocks 42 to be located therein. When the plug-in blocks 41 of the extended vibration plate 4 are located in the grooves 411, the positioning blocks 42 are plugged into the positioning grooves of the plug-in blocks 41, so that the plug-in blocks 41 can be fixed in the grooves 411, so that the extended vibration plate 4 can be installed and fixed together with the vibration plate 1, so that when the vibration plate 1 vibrates, it can also drive it to vibrate and compact, thereby increasing the compaction area of ​​the plate vibrator.

[0033] In addition, the bottom walls of the two connecting blocks 3 are provided with through holes for the positioning blocks 42 to pass through the interior thereof, and the left and right ends of the top of the vibration plate 1 are provided with connecting holes, which correspond to the connecting holes. The positioning blocks 42 are slidably connected to the inner sides of the through holes and the connecting holes, and the connecting holes are connected to the grooves 411, so that the positioning blocks 42 can be moved out of the connecting block 3 through the through holes and can be moved into the connecting holes of the vibration plate 1, so that the positioning blocks 42 can be moved into the grooves 411 of the vibration plate 1, which can facilitate the positioning blocks 42 to move into the positioning grooves of the plug-in block 41.

[0034] See also Figures 3 to 4 The pressing structure in this embodiment includes two vertical blocks 43, two groups of vertical plates 45, a horizontal bar 44 fixedly installed at the left and right ends of the vertical blocks 43, and a connecting plate 46 fixedly installed at the front ends of the two vertical plates 45 on the same side. The front end of the connecting plate 46 is rotatably connected to a screw 47 through a bearing.

[0035] Secondly, a pressing slot is provided on the opposite wall of the two vertical plates 45 of the same group for the cross bar 44 to pass through the interior thereof, and the two vertical blocks 43 are respectively fixed to the top ends of the two positioning blocks 42, so that the cross bar 44 can slide in the vertical plates 45 through the pressing slot. When the cross bar 44 moves to the lower end of the pressing slot, the cross bar 44 can push the positioning block 42 to move downward through the vertical block 43. Conversely, when the cross bar 44 moves to the top end of the pressing slot, the cross bar 44 can pull the positioning block 42 to move upward through the vertical block 43. Vertical sliding grooves are provided on the left and right walls of the inner cavity of the connecting block 3. The opposite ends of the two cross bars 44 of the same group are slidably connected to the inside of the vertical sliding groove, so that the vertical sliding groove can limit the cross bar 44 to ensure that the cross bar 44 can only move longitudinally.

[0036] In addition, the front ends of the two connecting blocks 3 are provided with threaded holes for allowing the screw 47 to pass through the interior thereof, so that the screw 47 can move in or out of the connecting block 3 through the threaded holes, so that the screw 47 can drive the connecting plate 46 to move back and forth in the connecting block 3, thereby enabling the connecting plate 46 to drive the two vertical plates 45 in the same group to move back and forth. The width of the positioning block 42 is smaller than the spacing between the left and right vertical plates 45 in the same group, so that when the positioning block 42 moves into the connecting block 3, it can be located between the left and right vertical plates 45 in the same group to prevent the two vertical plates 45 in the same group from obstructing the longitudinal movement of the positioning block 42.

[0037] See also Figure 4 The resistance structure in this embodiment also includes a pressure block 48 fixed to the front and rear ends of the vertical block 43, and the resistance structure also includes two vertical rods 49 fixed to the top walls of the inner cavities of the two connecting blocks 3, and the outer surfaces of the vertical rods 49 are sleeved with resistance springs 410.

[0038] At the same time, the top ends of the two groups of pressure blocks 48 are provided with round holes for the vertical rods 49 to pass through, so that the pressure blocks 48 can slide on the outer surface of the vertical rods 49 so that the pressure blocks 48 can squeeze the resistance springs 410 sleeved on the outer surface of the vertical rods 49. The top ends of the two positioning blocks 42 are provided with extension grooves for the vertical rods 49 to extend into the interior thereof, so that when the positioning blocks 42 move upward and move into the connecting block 3, the vertical rods 49 can extend into the positioning blocks 42, avoiding obstruction to the upward movement of the positioning blocks 42.

[0039] It should be noted that the vibration drive end 2 is well known to the public in the prior art, and the control method of the present invention is controlled by a controller. The electrical components appearing in the text are all connected to the controller and the power supply. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also well known in the art, so the control method and circuit connection are no longer explained in detail in this utility model.

[0040] The working principle of the above embodiment is:

[0041] When in use, when it is necessary to extend the vibration area of ​​the vibration plate 1, the two screws 47 are rotated so that the two screws 47 gradually move out of the connecting block 3, thereby allowing the screws 47 to drive the connecting plate 46 to move forward, so that the two connecting plates 46 can drive the two sets of vertical plates 45 to move forward, and the cross bar 44 moves from the bottom end of the pressing slot of the vertical plate 45 to the top end thereof, so that the two sets of cross bars 44 can pull the vertical block 43 to move upward, so that the vertical block 43 drives the two pressure blocks 48 of the same group to slide on the outer surface of the vertical rod 49, so that the pressure block 48 can squeeze the resistance spring 410 sleeved on the outer surface of the vertical rod 49, and the vertical block 43 moves upward. At the same time, the vertical block 43 can pull the positioning block 42 to move upward, so that the vertical rod 49 gradually moves into the extension groove of the positioning block 42, so that the positioning block 42 can move from the groove 411 of the vibration plate 1 to the connecting block 3;

[0042] The plug-in block 41 of the extended vibration plate 4 is inserted into the groove 411 of the vibration plate 1, and the two screws 47 are rotated so that the two screws 47 gradually move into the connecting block 3, so that the screws 47 can drive the connecting plate 46 to move backward, so that the two sets of vertical plates 45 move backward. During the backward movement of the vertical plates 45, the crossbar 44 moves from the top end of the pressing slot hole of the vertical plates 45 to the bottom end thereof, so that the vertical plates 45 can push the crossbar 44 to move downward, so that the two sets of crossbars 44 can push the two positioning blocks 42 to move downward through the two vertical blocks 43, so that the pressure block 48 no longer squeezes the resistance spring 410, and the resistance spring The spring 410 can act as a resistance to the positioning block 42 through the pressure block 48 and the vertical block 43, and the positioning block 42 is moved out of the connecting block 3 and into the groove 411 of the vibration plate 1, so that the positioning block 42 can be inserted into the positioning groove of the plug-in block 41, so that the plug-in block 41 can be fixed in the groove 411, and the extended vibration plate 4 can be fixed on the vibration plate 1, thereby increasing the vibration area of ​​the vibration plate 1, reducing the number of round trips when constructing a wider road surface, reducing the labor intensity of the operator, achieving the effect of improving construction efficiency, and improving the performance of the plate vibrator.
