Description

Technical Field

[0001] The utility model belongs to the technical field of construction machinery and relates to a fixing and supporting device for the engine base of an engineering dump truck. Background Technique

[0002] The ground transportation work of materials for construction engineering projects is usually completed by dump trucks suitable for the construction projects. The ground transportation tasks of earth-rock excavation materials and concrete materials are mainly borne by dump trucks. Affected by the road conditions of construction projects, most dump trucks are heavily loaded and going downhill. Based on the above factors, the service life of the fixing and supporting device for the front engine base (front engine foot pad) is relatively short, and it often breaks during operation. After breakage, the engine works under a suddenly unbalanced or unstable state, and components such as the radiator fan, radiator water tank, and input end cover of the gearbox installed in the engine part will be damaged. In the light case, the consumption cost of accessories will increase significantly, and in the heavy case, it will affect the safe operation state of mechanical equipment. Considering the above situation, it is necessary to design a fixing and supporting device for the engine base that is not easily damaged and can meet the performance requirements. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fixing and supporting device for the engine base of an engineering dump truck, which has the characteristics of increasing the stability and load-bearing strength of the base support frame and having good shock absorption effect.

[0004] The technical solution adopted by the utility model is that the fixing and supporting device for the engine base of an engineering dump truck includes a base support frame. The base support frame is an L-shaped plate, and grooves are opened on both sides of the base support frame. Reinforcing rib plates are welded in the grooves on both sides of the base support frame, and the base support frame is connected to a buffer pad through bolts.

[0005] The characteristics of the utility model also lie in:

[0006] The base support frame includes a side plate and a bottom plate.

[0007] The grooves are an upper groove opened along the edges of both sides of the inner surface of the bottom plate and a lower groove opened along the edges of both sides of the outer surface of the bottom plate.

[0008] The reinforcing rib plates include a pair of upper rib plates and a pair of lower rib plates. The upper rib plates and the lower rib plates are both right-angled triangles. One right-angled side of the two upper rib plates is respectively welded in the two upper grooves, and the other right-angled side of the two upper rib plates is welded to the side plate. One right-angled side of the two lower rib plates is respectively welded in the two lower grooves, and the other right-angled side of the two lower rib plates is aligned with the side plate.

[0009] The bottom of the buffer pad is provided with a groove a that is used in cooperation with the bottom plate.

[0010] The buffer pad is provided with bolt connection holes a in the middle, the bottom plate is provided with bolt connection holes b that cooperate with the bolt connection holes a, the side plate is provided with bolt connection holes c, and the base support frame and the buffer pad are bolted through the bolt connection holes a and b.

[0011] There are 4 bolt connection holes a, and the 4 bolt connection holes a are evenly and symmetrically distributed.

[0012] There are 6 bolt connection holes c, and the 6 bolt connection holes c are evenly distributed.

[0013] The 6 bolt connection holes c are symmetrically distributed along the midline where the side plate is perpendicular to the bottom plate.

[0014] The buffer pad is provided with a buffer ring groove parallel to the bottom plate along its outer periphery.

[0015] The beneficial effects of the present utility model are as follows:

[0016] By adding reinforcing rib plates, the connection structural strength of the bottom plate and the side plate of the base support frame is enhanced, and the stability and load-bearing strength of the base support frame are increased; grooves are respectively opened on the upper and lower surfaces of the bottom plate of the base support frame. The upper groove is used to strengthen the stable connection between the buffer pad and the base support frame, and the lower groove is convenient for the welding of the lower rib plate; the buffer pad is added. On the one hand, it connects the engine base and the base support frame, enabling the engine to be accurately and stably installed on the dump truck frame, ensuring the stable installation effect of the engine. On the other hand, it has a shock-absorbing effect. The buffer pad is made of a flexible material, which can play a shock-absorbing and stable dynamic effect when the dump truck is transporting materials and driving on a bumpy road surface, preventing the engine from being damaged due to rigid collision with the base support frame during operation.

[0017] The structure of the support and fixing device for the engine base of the dump truck is improved, making the installation connection between the engine and the vehicle frame more stable. Even when the dump truck is heavily loaded and going downhill, it can effectively maintain the dynamic stable operation state of the engine, improving the safety operation effect during the material transportation of the dump truck. Solve the technical problem of the original design defect of the support and fixing device for the engine base of the dump truck, reduce the safety operation failure rate of the dump truck, increase the service life of the support and fixing device for the engine base, reduce the accessory consumption cost, and achieve the effects of convenient installation and strong practicability.

[0022] The present utility model will be described in detail below with reference to the accompanying drawings and specific implementation modes.

[0023] The fixed support device for the engine base of an engineering dump truck, as Figure 1 and Figure 2 shown, the base support frame 1 includes a side plate 9 and a bottom plate 10, and the base support frame 1 is an L-shaped plate.

[0024] As Figure 2 shown, the upper groove 6 is opened along the two side edges of the inner surface of the bottom plate 10, and the lower groove 7 is opened along the two side edges of the outer surface of the bottom plate 10.

[0025] As Figure 1 and Figure 2 shown, both the upper rib plate 3 and the lower rib plate 4 are right-angled triangles. One right-angled side of the two upper rib plates 3 is respectively welded in the two upper grooves 6, the other right-angled side of the two upper rib plates 3 is welded to the side plate 9, one right-angled side of the two lower rib plates 4 is respectively welded in the two lower grooves 7, and the other right-angled side of the two lower rib plates 4 is aligned with the side plate 9.

[0026] As Figure 3 shown, the bottom of the buffer pad 2 is provided with a groove a 12 for cooperating with the bottom plate 10, and the buffer pad 2 is provided with a buffer ring groove parallel to the bottom plate 10 along its outer circumference.

[0027] As Figure 1 and Figure 2 shown, the buffer pad 2 is provided with bolt connection holes a 5 in the middle. There are 4 bolt connection holes a 5, and the 4 bolt connection holes a 5 are evenly and symmetrically distributed.

[0028] The bottom plate 10 is provided with bolt connection holes b 8 for cooperating with the bolt connection holes a 5, and the side plate 9 is provided with bolt connection holes c 11. There are 6 bolt connection holes c 11, and the 6 bolt connection holes c 11 are symmetrically distributed along the median line perpendicular to the bottom plate 10 of the side plate 9.

[0029] The base support frame 1 and the buffer pad 2 are bolt-connected through the bolt connection holes a 5 and the bolt connection holes b 8.

[0030] The working principle of the fixed support device for the engine base of the engineering dump truck provided by the present utility model is:

[0031] This dump truck engine has a total of 4 bases that need to be installed and fixed, so 4 sets of fixed support devices for the dump truck engine base are correspondingly required. Each base support frame 1 is provided with 6 bolt connection holes b8 and is firmly connected to the dump truck frame by bolts. This fixed support device for the dump truck engine base is the main load-bearing device for engine installation. It is composed of 2 upper rib plates 3 and 2 lower rib plates 4 welded on the base support frame 1 respectively, which increases the stability and load-bearing strength of the base support frame 1. Among them, the upper rib plate 3 is mainly welded on the base support frame 1, and the lower rib plate 4 is mainly welded on the dump truck frame and the base support frame 1.

[0032] The buffer pad 2 has a certain elasticity and is penetrated by 4 bolt connection holes a5 in the middle, and is connected to the engine base and the base support frame 1. The buffer pad mainly plays two roles. On the one hand, it connects the engine base and the base support frame 1, so that the engine can be accurately and stably installed on the dump truck frame, ensuring the stable effect of engine installation. On the other hand, it has a shock-absorbing effect. Because the buffer pad 2 is made of flexible material, when the dump truck is transporting materials and driving on a bumpy road surface, it can play a shock-absorbing and stabilizing dynamic effect, preventing the engine from being damaged due to rigid collision with the base support frame 1 during operation.

[0033] The upper and lower surfaces of the bottom plate 10 are respectively provided with grooves. The upper groove 6 is conducive to the welding and fixing of the upper rib plate 3. The bottom plate 10 abuts against the groove a12 on the buffer pad 2, playing a role of stable connection; the lower groove 7 is convenient for the welding of the lower rib plate 4. The upper groove 6 and the lower groove 7 on the upper and lower surfaces of the bottom plate 10 effectively improve the stable load-bearing strength of the base support frame 1.

[0034] The installation method of the fixed support device for the dump truck engine base is as follows:

[0035] The first step is to install the base support frame 1, which is installed and connected through the bolt connection holes b8 on the side plate 9 and the bolt connection holes on the dump truck frame. During implementation, the hole positions need to be accurately aligned and the installation force needs to be controlled;

[0036] The second step is to install the lower rib plate 4. After the base support frame 1 is installed, when the installation surfaces of the base support frame 1 and the dump truck frame are aligned, the lower rib plate 4 is welded and reinforced on both the left and right sides;

[0037] The third step is to install the upper rib plate 3. After aligning the installation surface of the upper rib plate 3 with the installation surfaces of the side plate 9 and the bottom plate 10, it is welded and reinforced on both the left and right sides;

[0038] The fourth step is to install the buffer pad 2. After sliding the buffer pad 2 into the bottom plate 10, align the bolt connection holes a5 and b8 and then connect them by bolts;

[0039] Step 5: Install the remaining three fixed support devices for the engine base of the engineering dump truck with reference to the previous steps;

[0040] Step 6: After all the fixed support devices for the engine base of the engineering dump truck are installed in place and the installation dimensions are checked to be correct, hoist the engine, align the bolt connection holes of the engine base with the hole positions of bolt connection hole b8 and bolt connection hole a5, and then implement the overall installation of the engine after following the engine specification hoisting regulations.
