[0002] Municipal roads refer to urban roads. Municipal roads are divided into five levels according to their position in the road network, traffic functions and service functions along the route: expressways, trunk roads, secondary trunk roads, branch roads and district roads (residential and industrial areas). Municipal roads are paved with concrete or asphalt.

[0003] Concrete pavement refers to a pavement with cement concrete slabs as the surface layer. It refers to a pavement structure composed of a cement concrete slab as the surface layer, a base layer and a cushion layer underneath. It is also called a rigid pavement. The road paved with concrete needs to be vibrated and leveled. The road can be vibrated and leveled as a whole using a concrete vibrating frame.

[0004] Due to the different road widths of existing municipal roads, the width of the vibrating frame needs to be adjusted according to the road width when using the vibrating frame. In the prior art, the width of the vibrating frame is often changed by modular assembly. However, the modularly assembled vibrating frame not only requires the transportation of multiple sets of vibrating frame modules, but also requires on-site splicing by staff, and the overall operation is relatively cumbersome.

DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] The following describes an embodiment of the present invention based on its overall structure.

[0028] A concrete vibrating device for municipal highway engineering, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, it includes a main body 1, fixed frames 2 are fixedly arranged on both sides of the top of the main body 1, and telescopic expansion frames 4 corresponding to the two groups of fixed frames 2 are slidably connected on one side of the main body 1, wherein hydraulic telescopic rods 3 are fixedly arranged at the triangular parts inside the two groups of fixed frames 2, and the output ends of the three groups of hydraulic telescopic rods 3 are fixedly connected to the telescopic expansion frames 4, and the ends of the three groups of hydraulic telescopic rods 3 are fixed with connecting pipes 13, and the three groups of connecting pipes 13 are connected with connecting heads 14, and a motor 11 is installed on the top of the fixed plate 21 and inside the control box 22, and a transmission rod 12 fixedly connected to a group of vibrating rods 903 is fixed at the output end of the motor 11, and fixed frames 18 are fixedly arranged on the bottom of both sides of the main body 1, and a fixed plate 21 is fixed on the top of one group of fixed frames 18, and a control box 22 is fixedly arranged on the top of the fixed plate 21, and the control box 22 is connected to the connecting head 14;

[0029] Both ends of the telescopic expansion frame 4 are fixed with connecting support plates 5, and a rotating rod 10 is rotatably connected between the two sets of connecting support plates 5. Two sets of sprocket wheels 6 are fixed at both ends of the outer sides of the rotating rod 10. Connecting support frames 7 are fixed at both ends of the telescopic expansion frame 4. Chains 8 are meshed and connected to the outer sides of each two sets of sprocket wheels 6, and the bottom and top ends of the chain 8 are respectively fixedly connected to the fixed frame 2 and the connecting support frame 7. Multiple sets of vibrating mechanisms 9 are evenly fixedly arranged between the chains 8. The vibrating mechanisms 9 include a fixed rod 901, a matching frame 902, a vibrating rod 903, an eccentric block 904, a clamping plate 906, a clamping groove 907 and a vibrating plate 912. The vibrating plate 912 is fixed at the bottom of the matching frame 902 and is located below the vibrating rod 903.

[0030] Each set of vibrating mechanisms 9 is fixedly connected by a fixed rod 901 and a chain 8, a matching frame 902 is fixed on the outside of each set of fixed rods 901, and a vibrating rod 903 is rotatably connected inside each set of matching frames 902. Eccentric blocks 904 are fixed on both sides of the outside of each set of vibrating rods 903, and the clamping plates 906 and the clamping grooves 907 are respectively located on both sides of the two sides of the vibrating rods 903, and the clamping plates 906 and the clamping grooves 907 cooperate with each other. Through multiple sets of hydraulic telescopic rods 3, the telescopic expansion frame 4 can be driven to extend relative to the fixed frame 2. The extended telescopic expansion frame 4 drives multiple groups of sprockets 6 to move through the connecting support plate 5, and drives the end of the upper part of the chain 8 to move synchronously through the connecting support frame 7, so that the upper part of the chain 8 is unfolded, and the end of the lower part of the chain 8 is fixedly connected to the fixed frame 2, wherein multiple groups of vibrating mechanisms 9 are evenly fixedly arranged inside the chain 8. When the chain 8 is extended and unfolded, the vibrating mechanism 9 is driven to rotate from the upper part to the lower part, thereby increasing the vibrating mechanism 9 contacting the concrete road surface, thereby increasing the width of the road surface vibration;

[0031] The vibrating mechanism 9 also includes a spring 905, a limit rod 908, a limit block 909, a mounting groove 910 and a bearing 911. The snap plate 906 and the vibrating rod 903 are elastically connected by the spring 905. When a group of vibrating mechanisms 9 rotates to the bottom, if this group of snap plates 906 is in a misaligned state with the previous group of snap grooves 907, the snap plates 906 are in a contracted state under the action of the spring 905. At this time, the snap plates 906 are contracted to the inside of the mounting groove 910. When the remaining vibrating rods 903 at the bottom rotate, the snap grooves 907 rotate relative to the snap plates 906. When the snap grooves 907 rotate to the position aligned with the snap plates 906, When at the corresponding position, the locking plate 906 is inserted into the locking groove 907 under the resetting action of the spring 905, so that the vibrating rod 903 is locked and connected, and can be rotated as a whole. A limiting rod 908 extending to the inside of the vibrating rod 903 is fixed on the inner side of the locking plate 906, and a limiting block 909 extending to the inside of the vibrating rod 903 is fixed on the outer side of the limiting rod 908. The limiting rod 908, the limiting block 909 and the vibrating rod 903 are axially slidably connected. The vibrating rod 903 and the matching frame 902 are rotationally connected via a bearing 911. An installation groove 910 matching the locking plate 906 and the spring 905 is provided on one side of the inside of the vibrating rod 903.

[0032] See also Figure 1 and Figure 2 Both ends of the outside of the two sets of fixed frames 2 are fixed with support plates 15 located at the bottom of the connecting support frame 7, and both ends of the inside of the two sets of fixed frames 2 are fixed with limit plates 16 that cooperate with multiple sets of vibrating plates 912. The present invention sets the above structure, wherein the support plate 15 plays a supporting role for the connecting support frame 7, and the limit plate 16 plays a supporting role for multiple sets of upper vibrating plates 912.

[0033] See also Figure 6 and Figure 7 Both ends of the bottom side of the telescopic expansion frame 4 are fixed with telescopic plates 17 extending into the interior of the main body 1, and through holes matching the telescopic plates 17 are opened at both ends of the interior of the main body 1. The present invention sets the above structure, wherein the telescopic plate 17 plays a stabilizing role when the telescopic expansion frame 4 is extended, making the telescopic expansion frame 4 more stable when it is extended.

[0034] See also Figure 1 Both ends of the two sets of fixed frames 18 are fixed with hydraulic cylinders 19 with the output ends facing downward, and the output ends of multiple sets of hydraulic cylinders 19 are fixed with universal wheels 20 located below the fixed frames 18. By setting the above structure, the present invention can move and adjust the position of the entire invention and adjust the height of the entire invention with the cooperation of the hydraulic cylinders 19 and the universal wheels 20.

[0035] The working principle of the present invention is as follows: when in use, the power is turned on, and the present invention is first pushed to the initial section of the concrete pavement as a whole. The staff adjusts the present invention as a whole according to the width of the pavement, and then according to the height of the concrete pavement, the multi-group hydraulic cylinder 19 is height-adjusted so that the universal wheels 20 are placed on both sides of the concrete pavement, so that the vibrating plates 912 of the vibrating mechanism 9 are in contact with the surface of the concrete pavement;

[0036] Specifically, the telescopic expansion frame 4 can be driven to extend relative to the fixed frame 2 through multiple sets of hydraulic telescopic rods 3, and the extended telescopic expansion frame 4 drives multiple sets of sprockets 6 to move through the connecting support plate 5, and drives the end of the upper part of the chain 8 to move synchronously through the connecting support frame 7, so that the upper part of the chain 8 is unfolded, and the end of the lower part of the chain 8 is fixedly connected to the fixed frame 2;

[0037] A plurality of vibrating mechanisms 9 are evenly and fixedly arranged inside the chain 8. When the chain 8 is extended and unfolded, the vibrating mechanisms 9 are driven to rotate from the upper part to the lower part, thereby increasing the vibrating mechanisms 9 contacting the concrete pavement, thereby increasing the width of the pavement vibration.

[0038] Furthermore, when one set of vibrating mechanisms 9 rotates downward, the two sets of vibrating mechanisms 9 are connected to each other through the two sets of vibrating rods 903, and the clamping plates 906 of the lower set of vibrating rods 903 are inserted into the clamping grooves 907 of the upper set of vibrating rods 903, so that the two sets of vibrating rods 903 are engaged and connected, so that the vibrating rods 903 of the extended and expanded vibrating mechanism 9 can rotate with the upper set of vibrating rods 903, and the rotating vibrating rods 903 generate vibration force under the action of the eccentric blocks 904 on their surfaces, so that the vibrating plates 912 vibrate the concrete;

[0039] As can be seen from the above, when the present invention is adjusted to adapt to road surfaces of different widths, the overall work efficiency is effectively improved, and the problem of needing to transport the modular vibrating frame is effectively avoided;

[0040] Specifically, the vibrating rods 903 between the multiple groups of vibrating mechanisms 9 permanently disposed at the lower part of the chain 8 are connected end to end through the clamping plate 906 and the clamping groove 907, and the vibrating rods 903 of the vibrating mechanism 9 close to the motor 11 are always connected to the transmission rod 12 of the motor 11, so that the vibrating rods 903 of the deployed vibrating mechanism 9 can be automatically plugged in and rotated to generate vibration force;

[0041] When a group of vibrating mechanisms 9 rotates to the bottom, if this group of engaging plates 906 is in a misaligned state with the previous group of engaging grooves 907, the engaging plates 906 are in a contracted state under the action of the spring 905. At this time, the engaging plates 906 are contracted to the inside of the installation groove 910. When the remaining vibrating rods 903 at the bottom rotate, the engaging grooves 907 rotate relative to the engaging plates 906. When the engaging grooves 907 rotate to the corresponding positions with the engaging plates 906, the engaging plates 906 are inserted into the engaging grooves 907 under the resetting action of the spring 905, so that the vibrating rods 903 are engaged and connected, and can rotate as a whole.

[0042] Furthermore, the width of each set of vibrating plates 912 can be set to different widths according to actual conditions, and thus the width of different numbers of vibrating plates 912 combined can adapt to road surfaces of different widths.

[0043] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
