DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In order to solve the technical problem that the tank body has no passive protection measures and is prone to safety hazards, the utility model provides a sewage suction truck with a safety support device, which can prevent the hydraulic system from failing and causing the tank body to fall, thereby causing safety accidents.

[0031] It should be noted that the sewage suction truck with a safety support device described in the present invention is used for but not limited to sewage suction trucks, etc. For the convenience of explanation, in the present invention, only a sewage suction truck with a safety support device is used in a sewage suction truck as an example for explanation. The principle of using a sewage suction truck with a safety support device in other types of equipment is essentially the same as the principle used in sewage suction trucks, and will not be repeated here.

[0032] See also Figure 1-Figure 5 ,in, Figure 1 This is a structural schematic diagram of a sewage suction truck with a safety support device in one embodiment of the present invention. The sewage suction truck with a safety support device includes a vehicle body 5, a vehicle plate 1, a tank body 2, a flipping mechanism 3 and a support rod 4. The vehicle plate 1 is installed on the vehicle body 5, and a plurality of grooves 11 are opened on the top of the vehicle plate 1 along the length direction of the vehicle plate 1. The tank body 2 is hinged to the top of the vehicle plate 1. The flipping mechanism 3 is installed on the top of the vehicle plate 1 and is used to drive the tank body 2 to flip. One end of the support rod 4 is hinged to the bottom of the tank body 2, and the other end of the support rod 4 is free to hang down in the direction of the groove 11 and is embedded in any groove 11.

[0033] In this embodiment, through the arrangement of the support rod 4 and several grooves 11, when the flipping mechanism 3 drives the tank body 2 to flip in the direction away from the vehicle plate 1, the end of the support rod 4 away from the tank body 2 cannot flip along with the tank body 2, but hangs freely and embeds into any groove 11, and then the end of the support rod 4 away from the tank body 2 is engaged with the groove 11, thereby achieving the purpose of the support rod 4 supporting the tank body 2, and the end of the support rod 4 away from the tank body 2 can replace different grooves 11 as the tank body 2 flips, so that the support rod 4 can always effectively support the tank body 2. When the hydraulic system fails, the support rod 4 can effectively replace the hydraulic system to support the tank body 2, thereby avoiding safety accidents caused by the direct fall of the tank body 2.

[0034] First, the flipping mechanism 3 is started, and the tank body 2 begins to flip in the direction away from the vehicle plate 1; then, the end of the support rod 4 away from the tank body 2 hangs freely due to its own gravity, and the support rod 4 flips in the opposite direction of the tank body 2, so that the end of the support rod 4 away from the tank body 2 is replaced with a different groove 11 for engagement, thereby enabling the support rod 4 to support the tank body 2; finally, when the tank body 2 is flipped and needs to be recycled, the staff lifts the support rod 4, releases the engagement between the end of the support rod 4 away from the tank body 2 and the groove 11, and the flipping mechanism 3 is started, and the tank body 2 can be flipped in the direction of the vehicle plate 1.

[0035] Preferably, the cross-sectional shape of the groove 11 is a right triangle, so that the end of the support rod 4 away from the tank body 2 can be replaced with a different groove 11 as the tank body 2 is turned over.

[0036] In one embodiment, see Figure 4-Figure 5 , both ends of the support rod 4 are provided with a limiting rod 21, and the two limiting rods 21 are fixedly connected to the bottom of the tank body 2.

[0037] In this embodiment, the function of the limiting rod 21 is to limit the left and right movement of the support rod 4, effectively preventing the support rod 4 from being misplaced and causing the end of the support rod 4 to be unable to fit into the groove 11.

[0038] In one embodiment, see Figure 4-Figure 5 A channel 211 is provided between the two limit rods 21 and the tank body 2 , and a moving rod 22 is provided below the support rod 4 . The moving rod 22 passes through the two channels 211 and can move back and forth along the length direction of the two channels 211 .

[0039] In this embodiment, the function of the moving rod is to realize the retraction and extension function of the support rod 4. When the moving rod moves along the length direction of the channel 211 to the hinge point between the support rod 4 and the tank body 2, the end of the support rod 4 can hang down freely and be embedded in any groove 11, and the end of the support rod 4 is embedded in different grooves 11 as the tank body 2 rotates away from the vehicle plate 1, thereby supporting the tank body 2 and effectively avoiding the safety hazard caused by the failure of the cylinder 32; when the moving rod moves along the length direction of the channel 211 to the end of the support rod 4, the end of the support rod 4 cannot hang down freely due to the abutment of the moving rod 22, which facilitates the flipping of the tank body 2 toward the vehicle plate 1.

[0040] Furthermore, a blind hole is provided at the end of the channel 211, and a spring is provided in the blind hole. A protrusion is fixedly connected to the upper part of the spring. The spring ensures that the protrusion always extends out of the blind hole. When the moving rod 22 is manually driven to pass over, the spring contracts and the protrusion is compressed into the blind hole. After the moving rod 22 passes over, the spring expands and the protrusion extends out of the blind hole, releasing the moving rod 22, so that the moving rod 22 can not slide along the length direction of the channel 211 under the support of the protrusion, and the end of the support rod 4 cannot droop freely under the restriction of the moving rod, thereby realizing the recovery of the support rod 4.

[0041] It should be noted that the length of the limit rod 21 needs to be greater than the support rod 4. When the end of the support rod 4 needs to be embedded in the groove 11, the moving rod needs to be moved to a position outside the hinge between the support rod 4 and the tank body 2 to avoid the moving rod affecting the free drooping of the end of the support rod 4.

[0042] In one embodiment, see Figure 4-Figure 5 The side walls of the moving rod 22 are fixedly connected to the limiting ring 221.

[0043] In this embodiment, the limiting ring 221 is used to ensure that the moving rod 22 does not escape from the channel 211 when moving along the length direction of the channel 211 .

[0044] In one embodiment, see Figure 4-Figure 5 Both ends of the moving rod 22 are fixedly connected with handles 222.

[0045] In this embodiment, the handle 222 is used to facilitate the staff to grasp the moving rod 22 so that the moving rod 22 can move along the length direction of the channel 211, thereby realizing the retraction and extension of the support rod 4.

[0046] In one embodiment, see Figure 1 There are two groups of turning mechanisms 3, and the two groups of turning mechanisms 3 are respectively located on both sides of the tank body 2.

[0047] In this embodiment, the turning mechanism 3 is provided in two groups, so that the tank body 2 is more stable during the turning process.

[0048] In one embodiment, see Figure 2 The flipping mechanism 3 includes a first articulated frame 31, a cylinder 32 and a protrusion 33. The protrusion 33 is fixedly connected to the side wall of the tank body 2. The first articulated frame 31 is fixedly connected to the top of the vehicle plate 1. The two ends of the cylinder 32 are hinged to the first articulated frame 31 and the protrusion 33 respectively.

[0049] In this embodiment, the cylinder 32 is a single-axis cylinder, the fixed end of the cylinder 32 is hinged to the first hinge frame 31, and the output end of the cylinder 32 is hinged to the protrusion 33. The tank body 2 can realize a flipping movement according to the operation of the cylinder 32, which is convenient for draining the material in the tank body 2.

[0050] In one embodiment, see Figure 4-Figure 5 The end of the tank body 2 is fixedly connected to a hinge rod 23 , the top of the vehicle plate 1 is fixedly connected to a second hinge frame 12 , and the hinge rod 23 is rotatably sleeved on the second hinge frame 12 .

[0051] In this embodiment, the second hinged frames 12 are arranged in pairs on both sides of the tank body 2, and the two ends of the hinged rod 23 are rotatably sleeved on the two second hinged frames 12, so that when the flipping mechanism 3 is in operation, the tank body 2 can flip with the hinged rod 23 as the rotation axis.

[0052] In one embodiment, see Figure 2 The end of the vehicle plate 1 is fixedly connected with a material guide plate 13.

[0053] In this embodiment, the function of the material guide plate 13 is to guide the material discharged from the tank body 2 to a specified direction.

[0054] In one embodiment, see Figure 4-Figure 5 The bottom of the tank body 2 is fixedly connected to a third hinge frame 24 , and the end of the support rod 4 is hinged to the third hinge frame 24 .

[0055] In this embodiment, the end of the support rod 4 is rotatably embedded in the third hinge frame 24 , so that the support rod 4 will not be separated from the third hinge frame 24 when rotating.

[0056] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0057] That is, the clamping connection between the end of the support rod 4 away from the tank body 2 and the groove 11 is released, and the cylinder 32 is started, and the tank body 2 is flipped toward the vehicle plate 1.

[0058] The above specific implementation methods of the present invention do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
