Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing structures, in particular to a diesel engine shock-absorbing connecting sleeve. Background Art

[0002] The installation position of the diesel engine shock-absorbing connecting sleeve mainly depends on the specific structure and installation environment of the diesel engine. Usually, the diesel engine shock-absorbing connecting sleeve will be installed between the supporting structure of the diesel engine and the ground or a fixed base. However, the effect of this type of shock-absorbing connecting sleeve is unsatisfactory and needs to be improved as follows: the diesel engine vibration transmission effect is poor, and the vibration is generally only absorbed and alleviated through the contact between the diesel engine base and the shock-absorbing connecting sleeve; the installation stability is insufficient, and the diesel engine is fixed to the supporting structure and the ground or a fixed base, and the fixing effect is not good only through the support and installation of the diesel engine base. Therefore, we propose a diesel engine shock-absorbing connecting sleeve. Utility Model Content

[0003] In order to solve the above shortcomings and deficiencies of the prior art, the purpose of the utility model is to provide a diesel engine shock absorbing connecting sleeve.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A diesel engine shock-absorbing connecting sleeve comprises a connecting sleeve assembly and a fixing assembly, wherein the interior of the connecting sleeve assembly is used for installing a diesel engine base, and the fixing assembly is installed on the connecting sleeve assembly to fix the diesel engine base;

[0006] The connecting sleeve assembly includes a mounting seat and a shock-absorbing sleeve, wherein the mounting seat is formed by two semicircular arc structures connected together, the mounting seat and the shock-absorbing sleeve are circular structures, the shock-absorbing sleeve is bonded to the inner circumferential wall of the mounting seat, and the shock-absorbing sleeve contacts the outer edge of the lower part of the diesel engine;

[0007] The fixing assembly includes a fixing frame and a positioning frame. The fixing frame has two groups installed between two semicircular arc structures and then installed on the seat. A plurality of hexagonal nuts are threadedly connected to the fixing frame. The threaded ends of the hexagonal nuts penetrate the fixing frame and are provided with rotating sleeves. The rotating sleeves are built into the adjusting groove inside the positioning frame. The hexagonal nuts are rotated forward and backward to drive the rotating sleeves to rotate in the adjusting groove. At the same time, the positioning frame is lowered / raised as the thread height of the hexagonal nut is adjusted. The rotating hexagonal nut completely contacts the fixing frame and the rotating sleeve contacts the inner bottom surface of the adjusting groove.

[0008] Furthermore, the bottom ends of the inner and outer circumferential walls of the mounting seat are both provided with ring seats facing outwards, and the ring seats are provided with mounting holes, so that the outer ring seat is used to fix the mounting seat to the mounting surface, and the inner ring seat is used to install the diesel engine base.

[0009] Furthermore, a card interface is provided on the end surface of the mounting seat, and the card interface is used for the positioning frame to be inserted.

[0010] Furthermore, on both sides of the two ends of the positioning frame located at the card interfaces, there are card convex blocks. The positioning frame is clamped in the card interfaces through the card convex blocks, and the fixing frame and the mounting seat are sequentially fastened through bolts.

[0011] Furthermore, the mounting seat is docked through a card slot and a card block, and the card slot and the card block are staggered on two semi-circular arcs.

[0012] Furthermore, a notch is opened at the bottom of the positioning frame, and the notch is docked with the diesel engine base.

[0013] Furthermore, a rubber pad is bonded to the bottom of the positioning frame.

[0014] Furthermore, the rotating sleeve rotates inside the adjusting groove, and the thickness of the adjusting groove is greater than the thickness of the rotating sleeve.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By bonding a shock-absorbing sleeve on the inner circumferential wall of the mounting seat, the outer edge of the lower part of the diesel engine is in close contact with the shock-absorbing sleeve. This design effectively enhances the conduction effect of the vibration of the diesel engine, so that the vibration can be better absorbed and alleviated through the shock-absorbing sleeve, thereby reducing the vibration amplitude of the diesel engine and improving the operation stability and reliability.

[0017] 2. The mounting seat is fixed to the ground, and the diesel engine is mounted on the mounting seat. Combining the designs of the fixing frame and the positioning frame, through the hexagonal nut and the rotating sleeve connected by threads, the positioning frame can be adjusted in height as needed to ensure the close fit and stable fixation between the diesel engine base and the support structure. The diesel engine base is stably mounted between the connecting sleeve assembly and the fixing assembly. At the same time, the setting of the card interface and the card convex block further enhances the stability of the connecting sleeve, prevents the diesel engine from shaking and displacing during operation, and further enables the vibration to be better absorbed and alleviated through the rubber pad, reducing the vibration amplitude of the diesel engine.

[0034] The rotating sleeve 24 rotates inside the adjusting groove 25 , and the thickness of the adjusting groove 25 is greater than the thickness of the rotating sleeve 24 .

[0035] It should be noted that the requirements of different models of diesel engines (with bases, i.e., legs) or different installation environments (fixed installation) can be met by adjusting the structure and size of the connecting sleeve assembly and the fixing assembly.

[0036] Example 2

[0037] like Figures 1-4 As shown, the bottom ends of the inner and outer circumferential walls of the mounting seat 11 are both provided with ring seats 13, and the ring seats 13 are provided with mounting holes 131, so that the outer ring seat 13 is used to fix the mounting seat 11 to the mounting surface, and the inner ring seat 13 is used for diesel engine base installation, and the size model of the mounting hole 131 is designed according to requirements.

[0038] A card interface 14 is provided on the end face of the mounting seat 11, and the card interface 14 is used for the positioning frame 22 to be inserted. Both ends of the positioning frame 22 are located on both sides of the card interface 14 and are provided with card protrusions 221. The positioning frame 22 is card-engaged in the card interface 14 through the card protrusions 221, and the fixing frame 21 and the mounting seat 11 are fastened in sequence by bolts, thereby connecting the mounting seat 11.

[0039] A notch 222 is provided at the bottom of the positioning frame 22, and the notch 222 is connected to the diesel engine base. A rubber pad 223 is bonded to the bottom of the positioning frame 22, and the rubber pad 223 contacts the notch 222 after connecting to the diesel engine base, and acts as a buffer, further reducing the impact of vibration on the diesel engine and its surrounding equipment.

[0040] The working process of the utility model is as follows: firstly, the two semi-circular arc structure mounting seats 11 of the connecting sleeve assembly 1 are connected through the card groove 111 and the card block 112 to ensure that they are tightly connected, and the connecting sleeve assembly 1 is placed in a predetermined installation position, and the mounting seat 11 is fixed to the mounting surface (such as the ground or a fixed base) by bolts or other fasteners through the mounting holes 131 on the ring seat 13 at the bottom ends of the inner and outer circumferential walls of the mounting seat 11. At the same time, the inner ring seat 13 is used for the installation of the diesel engine base, and then the fixing frame 21 of the fixing assembly 2 is installed on the mounting seat 11 between the two semi-circular arc structures, and the positioning frame 22 is inserted into the card interface 14 on the end face of the mounting seat 11 through the card connection protrusions 221 at both ends thereof, and the fixing frame 21 and the mounting seat 11 are tightened in sequence with bolts to ensure that the positioning frame 22 is firmly installed on the connecting sleeve assembly 1, and then Install the diesel engine in the connecting sleeve assembly 1 and the fixing assembly 2.
