A concrete mixing device for bridge and road construction

Abstract

This utility model discloses a concrete mixing device for bridge and road construction, including a frame, a mixing drum, and moving wheels. Each moving wheel on the frame has a positioning structure, which includes a bracket with a screw cylinder vertically threaded into it. The bottom end of the screw cylinder is rotatably connected to a positioning block. A double-ended screw is rotatably mounted on the side wall of the bracket corresponding to the circumference of the moving wheel. A pair of clamping plates are symmetrically screwed onto the two threaded sections of the double-ended screw to clamp the end face of the moving wheel. This utility model sets four sets of positioning structures corresponding to four moving wheels. By turning the screw cylinder, the positioning block is driven to contact the ground, increasing the friction with the ground. When the double-ended screw is turned, the clamping plates can be driven to clamp the side of the moving wheel to prevent it from rolling. Turning the screw can also drive the positioning rod into the soil for better locking and positioning, effectively increasing the stability of the entire equipment in complex working conditions such as bridge and road construction.

Description

Technical Field

[0001] This utility model relates to the technical field of concrete mixing equipment, and in particular to a concrete mixing device for bridge and road construction. Background Technology

[0002] Concrete is a product made by mixing cement as a binder, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion using a mixing equipment. It is widely used in infrastructure construction.

[0003] In the existing technology, some concrete mixing equipment is generally equipped with auxiliary wheels to facilitate turnover and movement on the construction site. However, for the many types of concrete mixing equipment on the market, although they can meet the requirements of mixing concrete, the road surface is not smooth for construction sites such as bridges and roads. The concrete equipment equipped with wheels has insufficient positioning stability during operation and is prone to displacement.

[0004] To address these issues, we propose a concrete mixing device for bridge and road construction. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete mixing device for bridge and road construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A concrete mixing device for bridge and road construction includes a frame, a mixing drum, and moving wheels. Each moving wheel on the frame is provided with a positioning structure. The positioning structure includes a bracket, and a screw cylinder is vertically threaded into the bracket. The bottom end of the screw cylinder is rotatably connected to a positioning block. A double-ended screw is rotatably installed on the side wall of the bracket corresponding to the circumference of the moving wheel. A pair of clamping plates are symmetrically threaded onto the two threaded sections of the double-ended screw for clamping the end face of the moving wheel.

[0008] In a further embodiment, a toothed ring is fixed on the outer circumferential sidewall of the stirring cylinder, and a motor and a drive gear are mounted on the frame, with the drive gear meshing with the toothed ring.

[0009] In a further embodiment, a pair of auxiliary frames are symmetrically installed on both sides of the frame, and auxiliary wheels are rotatably installed inside the auxiliary frames, with the portion of the auxiliary wheels protruding from the auxiliary frames in close contact with the outer wall of the mixing drum.

[0010] In a further embodiment, the side of the bracket is provided with a sliding groove, and the end of the clamp plate near the sliding groove is provided with a slider that extends into the sliding groove and slides.

[0011] In a further embodiment, a screw rod is threaded through and screwed into the interior of the cylinder, and a positioning rod is provided at the bottom end of the screw rod.

[0012] In a further embodiment, the positioning rod adopts a spiral conical head.

[0013] In a further embodiment, the bottom surface of the positioning block is connected to an anti-slip pad one, and the opposite sides of the clamping plate are each connected to an anti-slip pad two.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model is equipped with four sets of positioning structures corresponding to four moving wheels. By turning the screw, the positioning block can be driven to contact the ground, increasing the friction with the ground. When the double-ended screw is turned, the clamping plate can be driven to clamp the side of the moving wheel to prevent the moving wheel from rolling. The positioning rod can also be driven to screw into the soil by turning the screw for better locking and positioning, effectively increasing the stability of the entire equipment in complex working conditions such as bridge and road construction.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-2 A concrete mixing device for bridge and road construction includes a frame 1, a mixing drum 2, and moving wheels 3. The mixing drum 2 is rotatably mounted on the frame 1. The mixing drum 2 adopts a common double-cone drum. It mixes materials when rotating forward and discharges materials when rotating in reverse. A toothed ring 21 is fixed on the outer circumferential side wall of the mixing drum 2. A motor 23 is mounted on the frame 1. The output shaft of the motor 23 is connected to a drive gear 22, and the drive gear 22 meshes with the toothed ring 21. The mixing drum 2 is driven to rotate through the transmission action between the motor 23, the drive gear 22, and the toothed ring 21. Furthermore, in order to improve its rotational stability, a pair of auxiliary frames 24 are symmetrically installed on both sides of the frame 1. There is a gap between the auxiliary frames 24 and the mixing drum 2, and they do not directly contact each other. An auxiliary wheel 25 is rotatably mounted inside the auxiliary frame 24, and the part of the auxiliary wheel 25 protruding from the auxiliary frame 24 is in close contact with the outer wall of the mixing drum 2. This provides auxiliary support for the mixing drum 2, and the rotation of the auxiliary wheel 25 assists in the rotation of the mixing drum 2.

[0025] Please see Figure 3-4Each movable wheel 3 on the frame 1 is provided with a positioning structure, which includes a bracket 4. The bracket 4 adopts an L-shaped structure and is fixed to the frame 1. A screw cylinder 5 is screwed vertically to one end of the bracket 4 that extends out of the frame 1. The bottom end of the screw cylinder 5 is rotatably connected to a positioning block 6. The positioning block 6 adopts a frustum-shaped structure that is narrow at the top and wide at the bottom, which enhances the friction between the entire equipment and the ground when in contact with the ground. A double-ended screw 7 is rotatably installed on the side wall of the bracket 4 corresponding to the circumference of the movable wheel 3. The double-ended screw 7 is parallel to the axis of the movable wheel 3. The two threads of the double-ended screw 7 A pair of clamping plates 8 are symmetrically screwed onto the segment. Specifically, the side of the bracket 4 near the clamping plate 8 is provided with a groove 41 parallel to the axis of the double-ended screw 7, and the end of the clamping plate 8 near the groove 41 is provided with a slider 81 that extends into the groove 41 to slide, so as to limit the clamping plate 8 and prevent it from deflecting. Since the two threaded segments of the double-ended screw 7 have opposite thread directions, when the double-ended screw 7 rotates, it drives the pair of clamping plates 8 to move closer or further away from each other. When they are close, they are used to clamp the end face of the moving wheel 3, thereby locking the moving wheel 3 and preventing it from continuing to roll, thus enhancing stability.

[0026] Please see Figure 3-4 The screw barrel 5 has a screw rod 9 threaded through and screwed into its interior. The bottom end of the screw rod 9 is provided with a positioning rod 10. The screw barrel 5 is open from top to bottom, and the top end of the screw barrel 5 is provided with a threaded screw interface. The inner diameter of the threaded screw interface is smaller than the inner diameter of the through hole in the screw barrel 5. The positioning block 6 also has a through hole to facilitate the positioning rod 10 to pass through. The positioning rod 10 adopts a spiral cone head so that when used on soil surfaces, the positioning rod 10 can be screwed into the ground to improve the positioning effect.

[0027] Please see Figure 3-4 The bottom surface of the positioning block 6 is connected to an anti-slip pad 61, and the opposite sides of the clamping plate 8 are connected to anti-slip pads 82. The anti-slip pads are made of rubber or silicone.
