Description

Technical Field

[0001] This utility model relates to the technical field of construction machinery, and in particular to the technical field of auxiliary protective handles for concrete vibrators. Background Technology

[0002] A concrete vibratory pump is a core piece of equipment used in construction to compact concrete. It uses high-frequency vibration generated by a vibratory pump to remove air bubbles from the concrete, thereby improving its density and strength. Most concrete vibratory pumps on the market today have a smooth cylindrical or square structure, with some models featuring grooves on both sides of the pump body.

[0003] However, in actual operation, especially when moving, handling, or adjusting the angle of the vibratory pump, the above-mentioned structure has significant problems: operators are often forced to drag the power cable of the vibratory pump directly or barely hold the smooth pump body with their hands, which can easily damage the cable and cause serious safety hazards; at the same time, the smooth pump body is very easy to slip and drop, which may lead to equipment falling or personal injury. Even if there are grooves on both sides of the pump body, these grooves are not suitable as the main, repetitive hand-held force points due to their structure, size, location, or surface condition, making it impossible to complete the handling operation safely and effortlessly.

[0004] Therefore, the existing structure of vibratory pumps brings inconvenience and safety hazards to operators in practical applications, and there is an urgent need for an auxiliary device that can solve the above problems and provide operators with a safe, convenient and reliable gripping point. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the smooth surface of the vibratory pump of the concrete vibrator, which is difficult to hold, poses a risk of slippage during handling, and makes it difficult to install auxiliary components. The present invention proposes an auxiliary protective handle for the concrete vibrator, which achieves safe, reliable, and rapid installation and user-friendly operation by setting a bottom load-bearing structure with square support blocks, a graded guide positioning system with long and short positioning rods, and a lower-mounted L-shaped connector.

[0006] To achieve the above objectives, this utility model proposes an auxiliary protective handle for a concrete vibrator. 1. It includes a pair of symmetrically arranged handle bodies, wherein the handle body is a ring-shaped frame structure, which is used to fix and install on both sides of the vibratory pump of the concrete vibrator by fasteners. The ring-shaped frame structure is formed by connecting a rectangular part on the rear side and an isosceles trapezoidal part on the front side. The bottom transverse member of the ring frame structure has an integrally formed or fixedly connected main support structure block that protrudes towards the vibrating pump. At the bottom of the main support structure block, a square support block extending towards the vibrating pump is fixedly connected. The main support structure block has a weight reduction structure inside, and multiple first cylindrical protrusions are provided on the side facing the vibration pump; the first cylindrical protrusions have first light holes for fastening bolts to pass through. The upper inner wall of the ring frame structure is connected to an L-shaped connector. The vertical side of the connector is connected to the upper part of the frame, and its horizontal side extends towards the vibrating pump and is located inside the frame. The horizontal side itself forms a second cylindrical protrusion, and its interior is provided with a second light hole for fastening bolts to pass through. The main support structure block has a long positioning rod extending from its rear side and a short positioning rod extending from its front side, the length of the long positioning rod being greater than that of the short positioning rod. During installation, the vibration pump can be placed on the square support block to keep the handle body in a stable position perpendicular to the ground; the long positioning rod and the short positioning rod are used to be inserted into the corresponding holes of the vibration pump for pre-positioning, so that the first cylindrical protrusion and the second cylindrical protrusion are aligned with the internally threaded mounting holes on the vibration pump, and are locked and fixed by screwing in the fastening bolts.

[0007] Preferably, the number of the first cylindrical protrusions is five.

[0008] Preferably, the weight-reducing structure is a weight-reducing hole or a hollow structure; further, the shape of the weight-reducing hole or hollow structure includes honeycomb, rectangle or combination thereof.

[0009] Preferably, the handle body is integrally molded from a high-strength material; further, the high-strength material includes metal or engineering plastic.

[0010] Preferably, the outer surface of the ring-shaped frame structure is covered with an anti-slip insulating layer.

[0011] The beneficial effects of this utility model are: The beneficial effect of this utility model is that, compared with the prior art, it effectively solves the practical problems in the handling and operation of concrete vibratory machines through structural innovation, specifically manifested as follows: 1. Easy installation and labor-saving operation: The unique combination of square support blocks and long and short positioning rods enables rapid guidance and self-stabilizing positioning during installation. This structure makes it easy to align the heavy vibratory pump during installation, allowing for operation by a single person, significantly reducing installation difficulty and labor intensity.

[0012] 2. Reliable connection and high safety: The multi-bolt rigid connection, combined with a reinforced bottom support structure, allows the handle to stably withstand the weight of the equipment and operational impacts. This avoids the safety risks of dragging cables or holding a smooth pump body, significantly improving operational safety.

[0013] 3. Rational structure and strong practicality: The overall design balances strength and lightweight requirements, and the hollowed-out weight-reducing structure reduces weight while ensuring load-bearing capacity. The L-shaped connector design intelligently avoids existing components of the equipment, ensuring comfortable and interference-free grip, and has excellent practicality and ergonomic characteristics.

[0018] The working process of this utility model: The auxiliary protective handle for this concrete vibrator is described in conjunction with the accompanying drawings during operation.

[0019] like Figures 1 to 4 As shown, this utility model provides an exemplary embodiment of the left handle body 1, the structure of which is symmetrical about the central plane, and the right handle body is a mirror structure that is completely symmetrical about the central plane.

[0020] The handle body 1 is formed by connecting a rectangular portion 1a on the rear side and an isosceles trapezoidal portion 1b on the front side. The handle body 1 is made of a high-strength material through a one-piece molding process, and the high-strength material can be engineering plastic or metal.

[0021] At its bottom, a main support structure block 2 is integrally connected. At the bottom of the main support structure block 2, a square support block 7 extending towards the vibratory pump is fixedly connected. This square support block 7 is used to support the weight of the vibratory pump during installation, so that the entire handle body 1 maintains a stable posture perpendicular to the ground.

[0022] The main support structure block 2 has a weight-reducing structure 2a inside. The weight-reducing structure 2a is a weight-reducing hole or a hollow structure. Its shape can be honeycomb, rectangular or a combination thereof, so as to achieve a balance between lightweight and high strength.

Lift the vibratory pump and align it with the holes on its side corresponding to the long positioning rod 5, achieving initial engagement and rough positioning. Then, continue adjusting the pump body angle and align the short positioning rod 6 with its corresponding holes to complete precise positioning. At this point, the weight of the vibratory pump is supported by the square support block 7, and all the first cylindrical protrusions 3 and the second cylindrical protrusions are aligned with the pre-drilled, internally threaded mounting holes on the side of the vibratory pump. Finally, pass the high-strength fastening bolts through the holes on the outside of the handle and screw them into the threaded holes of the vibratory pump, tightening them to the specified torque. The right handle is installed symmetrically in the same manner.

[0027] At this point, the weight and main operating load of the vibratory pump are transferred to the entire handle body 1 through the square support block 7 at the bottom, the first cylindrical protrusion 3, and the bolts, forming a strong and reliable rigid connection. The outer surface of the ring frame structure can also be covered with an anti-slip insulating layer to improve operating comfort.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
