Description

Technical Field

[0001] This utility model relates to the field of building construction equipment fixing technology, and in particular to a fixing device that facilitates fixing a concrete mixer. Background Technology

[0002] As a core piece of equipment in construction, concrete mixers are prone to displacement and shaking due to the high-frequency vibrations they generate during operation. Therefore, reliable fixing devices are essential to ensure operational safety and stability. Existing fixing devices are mostly specialized structures with fixed support spacing, making them difficult to adapt to the support leg spacing requirements of different mixer sizes. This results in poor versatility, requiring custom-made devices when replacing a mixer, increasing construction costs and time. Furthermore, traditional fixing devices lack effective shock absorption structures, allowing vibrations to be directly transmitted to the support surface. This not only easily causes equipment slippage but may also damage the ground structure. The resulting equipment shaking can also affect mixing quality and even lead to component loosening and malfunctions. In addition, some fixing devices rely on manual adjustment of the fixing components, which is cumbersome and lacks sufficient fixing precision, making it difficult to ensure stability during long-term operation and posing safety hazards.

[0003] Therefore, this utility model proposes a fixing device for easily fixing a concrete mixer to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0009] Each of the three support boxes has a mounting shell fixedly installed. A rotating shaft is rotatably installed inside each of the three mounting shells. Three take-up and untake-up rollers are fixedly installed on their respective rotating shafts. Steel wire ropes are fixedly wound around each of the three take-up and untake-up rollers. The free ends of the three steel wire ropes extend outside the mounting shells and are each fixedly fitted with a hook. The three support boxes are located below the concrete mixer, and the three support legs of the concrete mixer are respectively snapped onto the top of their respective support boxes. Multiple hanging points are fixedly installed on the outer periphery of the concrete mixer, and three hooks are detachably installed on their respective hanging points. The tension adjustment assembly is located on the three support boxes and the three mounting shells and is connected to the three rotating shafts.

[0010] Preferably, the spacing adjustment assembly includes a motor, a worm gear, and three worm wheels. Worm wheels are fixedly sleeved on the three rotating pins located below. The motor is fixedly installed on the support shell, and the worm gear meshing with the three worm wheels is fixedly installed on the output shaft of the motor.

[0011] Preferably, the support and buffer assembly includes three lifting plates and multiple buffer springs. Lifting plates are slidably installed on the inner sidewalls of the three support boxes. Multiple buffer springs that are fixedly connected to the inner top wall of the corresponding support box are fixedly installed on the top side of the three lifting plates. The top side of the three support seats is fixedly installed on the bottom side of the corresponding lifting plates.

[0012] Preferably, the support and buffer assembly further includes three damping rods. Each of the three support boxes has a damping rod fixedly installed on its top inner wall, and the bottom ends of the three damping rods are respectively fixedly installed on the top side of the corresponding lifting plate.

[0013] Preferably, the lifting adjustment assembly includes three internal threaded sleeves, three lead screws, and three guide rods. Internal threaded sleeves are rotatably mounted on each of the three support boxes, and lead screws are threadedly installed inside each of the three internal threaded sleeves. The bottom ends of the three lead screws are respectively fixedly installed on the top side of the corresponding universal wheels.

[0019] The beneficial effects of this utility model are:

[0020] This invention, by incorporating a spacing adjustment component, allows for flexible adjustment of the distance between the three support boxes according to the actual spacing requirements of the concrete mixer's support legs. This enables the device to adapt to concrete mixers of different specifications, greatly improving its versatility. Simultaneously, the buffer springs and damping rods in the support buffer component work together to effectively absorb and buffer impact forces when the concrete mixer vibrates during operation, preventing vibration from being transmitted to the support surface and causing the device to shake. The damping rods also suppress the rebound vibration of the buffer springs, further enhancing the device's stability. Furthermore, the threaded engagement between the inner threaded sleeve and the threaded rod in the lifting adjustment component, along with the guiding action of the guide rod and guide port, allows for precise control of the swivel casters' lifting. When the device needs to be moved, lowering the swivel casters allows for easy pushing; when fixed, raising the swivel casters allows the support boxes and support bases to contact the ground, and the anti-slip rubber pads at the bottom of the support bases effectively prevent the device from slipping.

[0021] The adjustable tension component drives the rotating shaft to take in and release the wire rope via the winding and unwinding rollers. It also adjusts the tightness of the connection between the hook and the concrete mixer's attachment point, ensuring the mixer is securely secured within the support box and preventing displacement during operation. Furthermore, the slot design on the top of the support box limits the movement of the mixer's support legs, further enhancing the overall stability and reliability of the structure. Through the coordinated operation of all components, this fixing device is easy to operate, highly adaptable, and provides a safe and stable working environment for the concrete mixer.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] Reference Figure 1-8 A fixing device for facilitating the fixing of a concrete mixer includes three support boxes 1 for supporting the concrete mixer 6, a support shell 2, three support bases 3, three casters 4, and three take-up and unwinding rollers 52.

[0034] Two parallel support rods 21 are hinged to each other on the side of the three support boxes 1 that are close to each other. Six rotating pins arranged in pairs are rotatably mounted on the support shell 2. The ends of the six support rods 21 that are away from the support box 1 are radially fixed on the corresponding rotating pins. Worm gears 203 are fixedly sleeved on the three rotating pins located at the bottom. A motor 201 is fixedly mounted on the support shell 2. A worm gear 202 that meshes with the three worm gears 203 is fixedly mounted on the output shaft of the motor 201. The distance between the three support boxes 1 can be adjusted as needed to adapt to the support requirements of concrete mixers 6 of different specifications and improve the versatility of the device.

[0035] Three support seats 3 are slidably installed on the corresponding support boxes 1. Lifting plates 31 are slidably installed on the inner side walls of the three support boxes 1. Multiple buffer springs 32, which are fixedly connected to the top inner wall of the corresponding support box 1, are fixedly installed on the top side of the three lifting plates 31. The top side of the three support seats 3 is fixedly installed on the bottom side of the corresponding lifting plates 31, which can provide effective support and buffering effect for the support seats 3. Damping rods 33 are fixedly installed on the top inner wall of the three support boxes 1. The bottom ends of the three damping rods 33 are fixedly installed on the top side of the corresponding lifting plates 31, which can assist the buffer springs 32 to play a better shock absorption and buffering role, and at the same time suppress the vibration phenomenon caused by the reaction force of the buffer springs 32, thereby avoiding large-amplitude shaking of the concrete mixer 6 during operation and enhancing the overall stability of the device.

[0036] Each of the three support boxes 1 is rotatably mounted with an internal threaded sleeve 41, and each of the three internal threaded sleeves 41 is threaded with a lead screw 42. The bottom ends of the three lead screws 42 are respectively fixedly mounted on the top side of the corresponding universal wheels 4. Each of the three lead screws 42 has a guide opening. Each of the three support boxes 1 is fixedly mounted with a guide rod 43 that passes through the corresponding guide opening. This can control the universal wheels 4 to adjust their height when the internal threaded sleeves 41 rotate, thereby facilitating the switching between the moving and fixed states of the device. At the same time, in order to facilitate the operator to rotate the internal threaded sleeves 41, each of the three internal threaded sleeves 41 is fixedly mounted with an adjusting wheel 411.

[0037] Each of the three support boxes 1 is fixedly mounted with a mounting shell 5. A rotating shaft 51 is rotatably mounted inside each of the three mounting shells 5. Three take-up and untake-up rollers 52 are respectively fixedly mounted on their corresponding rotating shafts 51. Steel wire ropes 53 are fixedly wound around each of the three take-up and untake-up rollers 52. The free ends of the three steel wire ropes 53 extend outside the mounting shell 5 and are respectively fixedly mounted with hooks 54. The three support boxes 1 are all located below the concrete mixer 6, and the three support legs of the concrete mixer 6 are respectively snapped onto the top of their corresponding support boxes 1. Multiple hanging points are fixedly mounted on the outer periphery of the concrete mixer 6, and the three hooks 54 are detachably mounted on their corresponding hanging points. The tops of the three support boxes 1... Motor 2 55 is fixedly installed on the inner wall of each of the three rotating shafts 51. Worm gear 2 57 is fixedly sleeved on each of the three mounting shells 5. Worm 2 56 that meshes with the corresponding worm gear 2 57 is rotatably installed on the bottom inner wall of each of the three mounting shells 5. The three worm 2 56 are respectively axially fixed on the output shaft of the corresponding motor 2 55. This enables the winding and unwinding operation of the winding roller 52 on the wire rope 53, thereby adjusting the tightness of the connection between the hook 54 and the hanging point. At the same time, it can ensure that a self-locking effect is achieved after adjustment, effectively ensuring that the concrete mixer 6 is more firmly and reliably fixed on the support box 1, and effectively preventing the mixer from shifting or shaking due to vibration and other factors during operation.

[0038] In this embodiment, in order to facilitate the retraction and extension of the caster 4 during the lifting and adjustment process, and to avoid motion interference between the caster 4 and the support box 1 when it is retracted upwards, a through opening is provided on the bottom inner wall of the support box 1 for the caster 4 to pass through.

[0039] In this embodiment, in order to prevent relative sliding between the support legs and the support box 1, thereby further improving the stability of the concrete mixer 6, the top of the support box 1 is provided with a slot that matches the support legs of the concrete mixer 6, and the three support legs of the concrete mixer 6 are respectively snapped into the corresponding slots.

[0040] In this embodiment, in order to increase the friction between the support base 3 and the support surface, effectively prevent the device from slipping due to the vibration generated by the concrete mixer 6 during use, further improve the overall stability of the device, and at the same time protect the support surface and prevent the support base 3 from directly contacting the support surface and causing abnormal wear, an anti-slip rubber pad is provided on the bottom side of the support base 3.

[0041] Both motor 1 (201) and motor 2 (55) are servo motors and are electrically connected to an external controller.

[0042] The content protected by this application does not involve improvements to software, circuits, and methods. The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.

[0043] Working principle: When in use, first connect the power supply and start the motor 201 through the external controller. The output shaft of the motor 201 drives the worm gear 202 to rotate. The worm gear 202 meshes with the three worm wheels 203, causing the three rotating pins located below to rotate synchronously. This drives the six support rods 21 to unfold or retract around the rotating pins, thereby adjusting the distance between the three support boxes 1 to match the distance between the support legs of the concrete mixer 6 to be fixed. Then, the three support legs of the concrete mixer 6 are respectively inserted into the slots on the top of the support box 1 to ensure that there is no relative sliding between the support legs and the support box 1.

[0044] Next, hooks 54 are hung on the corresponding attachment points on the concrete mixer. Then, motor 2 55 is started by the external controller. The output shaft of motor 2 55 drives worm gear 2 56 to rotate. Worm gear 2 56 meshes with worm wheel 2 57, driving shaft 51 to rotate. This causes take-up and unwinding roller 52 to wind up the wire rope 53, tightening the connection between hooks 54 and the attachment points on the outer periphery of the concrete mixer 6. The self-locking characteristics of the worm gear and worm wheel are used to maintain the current tension, preventing the mixer from shifting during operation.

[0045] Afterwards, the operator rotates the adjusting wheel 411, causing the inner threaded sleeve 41 to rotate. Under the guidance of the guide rod 43 and the guide port, the screw 42 drives the universal wheel 4 to move upward along the inner wall of the support box 1 until the universal wheel 4 is completely retracted into the through port. At this time, the anti-slip rubber pad at the bottom of the support seat 3 contacts the ground, increasing the friction to prevent the device from slipping. When the concrete mixer 6 vibrates during operation, the vibration is transmitted to the support box 1 through the support leg. The lifting plate 31 slides on the inner wall of the support box 1, and the buffer spring 32 absorbs part of the vibration energy under pressure deformation. At the same time, the damping rod 33 extends or shortens, which can suppress the rebound vibration of the buffer spring 32 and prevent the device from shaking significantly, thereby achieving stable fixation of the concrete mixer 6.

[0046] The foregoing has provided a detailed description of a fixing device for easily securing a concrete mixer, as provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
