Description

Technical Field

[0001] The utility model relates to the technical field of concrete vibrating trolleys, in particular to a chassis structure of a concrete vibrating trolley. Background Art

[0002] Concrete vibrating trolleys are mainly used for vibrating operations in concrete construction. Their chassis structure is the key part that supports and moves the entire equipment. The chassis of a concrete vibrating trolley is mainly composed of the following components: The frame is the skeleton of the chassis, usually welded from high-strength steel, with sufficient strength and rigidity to support the weight of the entire equipment and the various forces generated during operation. Suspension system: The suspension system is used to connect the frame and wheels, and plays a role in shock absorption and buffering. It usually includes springs, shock absorbers, suspension arms and other components, which can effectively absorb and disperse the impact caused by uneven road surface, improving the stability of the equipment and ride comfort. Drive system: The drive system includes components such as the engine, transmission, drive shaft, and drive axle, which are used to provide power and drive the wheels to rotate, allowing the concrete vibrating trolley to move on the construction site. Steering system: The steering system is used to control the steering of the wheels so that the equipment can travel along the predetermined route. It usually includes components such as the steering wheel, steering gear, and steering knuckle, which can achieve precise steering control.

[0003] The existing concrete vibrating trolley will generate large vibrations when multiple sets of vibrators are in operation. The fixed connection between the vibrator and the chassis cannot provide buffering when the vibrator generates large vibrations. After long-term use, the vibrator will be damaged, affecting its use. Therefore, it is particularly important to improve the existing chassis structure and design a new chassis structure for the concrete vibrating trolley to solve the above technical defects and improve the practicality of the overall chassis structure. Utility Model Content

Through the design of the first damping spring, the second damping spring and the third damping spring, the connecting plate can be effectively buffered. When the vibrator operates on the top of the connecting plate and the operation of multiple groups of vibrators produces large vibrations, it can be effectively buffered to prevent the vibrator from being damaged during long-term use, thereby affecting the use, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A chassis structure for a concrete vibrating trolley includes a chassis body, a connecting plate provided on the top of the chassis body, multiple buffer assemblies provided between the connecting plate and the chassis body, the buffer assemblies connected to the chassis body via a connecting shell, multiple reinforcing rods fixedly connected to the interior of the chassis body, and support rods provided on the outside of the chassis body;

[0009] As a preferred solution of the present invention, one end of the second rotating rod close to the connecting plate is rotatably connected to a sliding wheel, and both ends of the movable rod are fixedly connected to a guide rack.

[0010] As a preferred solution of the present invention, the outer side of the guide rack is meshedly connected with a guide gear, and the guide gear is rotationally connected to the first rotating rod.

[0013] As a preferred solution of the present invention, both ends of the first compression spring are slidably connected to limit blocks located inside the connecting shell, and the limit blocks extend to the inside of the connecting shell and are fixedly connected to the second compression spring.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] A chassis structure for a concrete vibrating trolley includes a chassis body 1, a connecting plate 2 provided on the top of the chassis body 1, multiple groups of buffer assemblies 3 provided between the connecting plate 2 and the chassis body 1, and the buffer assemblies 3 connected to the chassis body 1 via a connecting shell 4. Multiple groups of reinforcing rods 5 are fixedly connected to the interior of the chassis body 1, and support rods 6 are provided on the outside of the chassis body 1. The design of the reinforcing rods 5 and support rods 6 can increase the overall strength of the chassis body 1, thereby extending its service life.

[0025] The buffer assembly 3 is used to buffer the vibration received by the connecting plate 2, and the buffer assembly 3 is composed of a movable plate 7, a movable rod 8, two groups of first rotating rods 9, two groups of second rotating rods 10, multiple groups of first damping springs 11, second damping springs 12, two groups of third rotating rods 13, two groups of fourth rotating rods 14 and two groups of movable blocks 15. The movable plate 7 is fixedly connected to the bottom of the connecting plate 2, the movable rod 8 is slidably connected to the inside of the connecting shell 4, the two groups of first rotating rods 9 are respectively located at the two ends of the two groups of movable rods 8, the second rotating rod 10 is rotatably connected to the outside of the first rotating rod 9, multiple groups of first damping springs 11 are all fixedly connected to the four sides of the top of the connecting shell 4, the second damping spring 12 is fixedly connected to the bottom of the movable rod 8, the two groups of third rotating rods 13 are all rotatably connected to the bottom of the movable rod 8 and are located at the two ends of the two groups of second damping springs 12, the fourth rotating rod 14 is rotatably connected to the end of the third rotating rod 13 away from the movable rod 8, and the movable block 15 is fixedly connected to the outside of the fourth rotating rod 14 and away from the end of the third rotating rod 13.

[0026] Furthermore, the end of the first damping spring 11 away from the connecting shell 4 is fixedly connected to the connecting plate 2, and the end of the second rotating rod 10 away from the first rotating rod 9 is rotatably connected to the connecting block. The connecting block and the connecting shell 4 are slidingly connected, and a third damping spring 16 is fixedly connected between the connecting block and the connecting shell 4. When the connecting plate 2 is displaced, the first damping spring 11 is squeezed, and the connecting plate 2 can be buffered by the first damping spring 11. When the first rotating rod 9 is displaced, the second rotating rod 10 is driven to displace, so that the connecting block is displaced and the third damping spring 16 is squeezed. The second rotating rod 10 can be buffered by the third damping spring 16, so that the first rotating rod 9 is buffered.

[0027] Among them, the second rotating rod 10 is rotatably connected to the sliding wheel 17 at one end close to the connecting plate 2, and the two ends of the movable rod 8 are fixedly connected to the guide rack 18. The outer side of the guide rack 18 is meshed with the guide gear 19, and the guide gear 19 is rotatably connected to the first rotating rod 9. When the connecting plate 2 is displaced, the first rotating rod 9 is displaced through the sliding connection, driving the guide gear 19 to displace, and the guide gear 19 is guided by the guide rack 18 to guide the first rotating rod 9. When the first rotating rod 9 is displaced, the second rotating rod 10 is driven to displace, so that the connecting block is displaced.

[0028] Furthermore, the fourth rotating rod 14 and the moving block 15 are both slidingly connected to the connecting shell 4, and the second damping spring 12 is fixedly connected to the connecting shell 4 at one end away from the moving rod 8. When the connecting plate 2 is displaced, the moving rod 8 is driven to displace, squeezing the second damping spring 12. The second damping spring 12 can buffer the moving rod 8, so that the connecting plate 2 is buffered. Through the design of the first damping spring 11, the second damping spring 12 and the third damping spring 16, the connecting plate 2 can be effectively buffered. When the vibrator operates on the top of the connecting plate 2 and the operation of multiple groups of vibrators produces large vibrations, it can be effectively buffered to prevent the vibrator from being damaged during long-term use, thereby affecting its use.

[0029] Furthermore, both ends of the interior of the connecting shell 4 and the outsides of the two groups of moving blocks 15 are fixedly connected with a first compression spring 20, the inside of the first compression spring 20 is fixedly connected to the outside of the moving block 15, and both ends of the first compression spring 20 and the inside of the connecting shell 4 are slidably connected to the limiting block 21, and the limiting block 21 extends to the inside of the connecting shell 4 and is fixedly connected with a second compression spring 22. When the moving block 15 contacts the two groups of limiting blocks 21, the limiting block 21 is driven to move by the second compression spring 22, and the limiting block 21 is moved to the outside of the moving block 15 to limit the moving block 15, thereby preventing the moving block 15 from resetting too quickly, causing the connecting plate 2 to be vibrated again and causing damage to the vibrator. When the moving block 15 is reset, the first compression spring 20 can cooperate with the reset of the moving block 15.

[0030] In this embodiment, the implementation scenario is specifically as follows: when multiple groups of vibrators are in operation and generate large vibrations, the connecting plate 2 is displaced. When the connecting plate 2 is displaced, the first damping spring 11 is squeezed, and the connecting plate 2 can be buffered by the first damping spring 11. At the same time, when the connecting plate 2 is displaced, the first rotating rod 9 is displaced by the sliding connection, driving the guide gear 19 to displace, and the guide gear 19 is guided by the guide rack 18, so as to guide the first rotating rod 9. When the first rotating rod 9 is displaced, the second rotating rod 10 is driven to displace, so that the connecting block is displaced, and the third damping spring 16 is squeezed. The second rotating rod 10 can be buffered by the third damping spring 16, so as to buffer the first rotating rod 9. When the connecting plate 2 is displaced, the moving rod 8 is driven to displace, and the second damping spring 12 is squeezed. The moving rod 8 can be buffered by the second damping spring 12, so as to buffer the connecting plate 2 is buffered. Through the design of the first damping spring 11, the second damping spring 12 and the third damping spring 16, the connecting plate 2 can be effectively buffered. When the vibrator operates on the top of the connecting plate 2 and the operation of multiple groups of vibrators produces large vibrations, it can be effectively buffered to prevent the vibrator from being damaged during long-term use, which affects the use. When the moving rod 8 is displaced, the third rotating rod 13 is driven to displace, so that the fourth rotating rod 14 is displaced, and the moving block 15 is driven to displace. When the moving block 15 contacts the two groups of limit blocks 21, the limit block 21 is driven to displace by the second compression spring 22, and the limit block 21 is moved to the outside of the moving block 15, limiting the moving block 15 to prevent the moving block 15 from resetting too quickly, causing the connecting plate 2 to be vibrated again and causing damage to the vibrator. Compared with the existing chassis structure, the utility model can improve the overall practicality of the chassis structure through design.
