Description

Technical Field

[0001] This utility model belongs to the technical field of cutter suction dredger equipment, and in particular relates to an underwater mud pump motor mounting base. Background Technology

[0002] Cutter suction dredgers are important vessels used in dredging projects. Their working principle is as follows: the gantry of the vessel is lowered into the water, and the cutterhead assembly at the end of the gantry rotates to excavate the mud surface on the bottom of the water, mixing with the water to form mud. The mud is then lifted along the pipeline by the mud pump and enters the mud pipeline on the deck of the vessel. The mud is then transported ashore by a self-floating mud pipeline or by a barge. During the cutter suction operation, the gantry also swings left and right at a certain angle to achieve cutter suction operation over a certain width of area.

[0003] An underwater pumping device, consisting of a motor and a mud pump, is installed on the bridge of a cutter suction dredger. The motor drives the mud pump, creating a negative pressure environment within the suction port, allowing the mud excavated by the cutter assembly to enter. During operation, cutter suction dredgers may experience pipe and pump blockages under extreme conditions. Pipe blockage refers to the mud pipe being blocked by rocks or other debris, while pump blockage refers to the mud pump being blocked by rocks or other debris. Therefore, the construction process of a cutter suction dredger is accompanied by the maintenance and repair of the mud pump and pipes. During these maintenance and repair operations, the bridge is raised above the waterline, and maintenance personnel perform these activities on the bow platform. In existing technology, the mud pump and motor mounted on the bridge are generally installed using a direct fixing method, i.e., using strong bolts to directly connect the mud pump and motor. This method has the following problem: it is difficult to guarantee the accuracy of repeated installation during multiple disassembly and reassembly. Therefore, a new underwater mud pump and motor mounting base device needs to be developed and designed to solve the aforementioned technical problems. Utility Model Content

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0021] Please see Figure 1 This utility model discloses an underwater mud pump motor mounting base, comprising an integrated mud pump base 1 and a mud pump support 2. The mud pump base 1 is bolted to the cable tray. It also includes an integrated motor base 4 and a motor support 5, with the motor base 4 bolted to the cable tray. Once the mud pump base 1, mud pump support 2, motor base 4, and motor support 5 are installed and fixed to the cable tray, they are generally not disassembled. The mud pump assembly and motor assembly are then detached from this mounting base.

[0022] In fact, motor components rarely fail and require maintenance, while mud pump components require frequent maintenance due to problems such as pump blockage. Figure 1 As shown, the motor assembly includes a motor 9, and the mud pump assembly includes a mud pump 8. The output shaft of the motor 9 and the input shaft of the mud pump 8 are connected by a coupling 6. A shaft support seat 7 is installed on the pump shaft of the mud pump 8. In the existing installation method, the shaft support seat 7 and the motor 9 are directly installed and fixed to the cable tray with bolts. A mud pipe 10 is installed at the outlet of the mud pump 8.

[0023] In this embodiment, the top of the motor base 4 is welded to the bottom of the motor support 5, and the bottom of the motor 9 is fixedly connected to the motor support 5 with bolts. The motor base 4 and the motor support 5 are both made of welded steel plates. Multiple mounting holes are provided on the bottom plate of the motor base 4, and the motor base 4 is fixedly connected to the profile of the cable tray with high-strength bolts located in each mounting hole.

[0024] Please see Figure 2 and Figure 3 It can be seen that:

[0025] The mud pump base 1 includes two opposing base plates 1-1. An outer base plate 1-3 is welded above the outer edge of the base plate 1-1. Multiple reinforcing housings 1-4 are welded along the length of the inner side of the outer base plate 1-3. The bottom of each reinforcing housing 1-4 is welded and fixed to the base plate 1-1. In this embodiment, the reinforcing housing 1-4 includes a high-level housing and a low-level housing, which are spaced apart. A lifting lug 1-5 is welded to the top of the low-level housing. Figure 2 As shown, the height of the higher-level housing is greater than the height of the lower-level housing. The higher-level housing has two sections, one at the front and one at the back, and the lower-level housing also has two sections, one at the front and one at the back. The purpose of the lifting lugs 1-5 is to facilitate the lifting and transfer of the mud pump base 1 and the mud pump support 2 using a crane.

[0026] The mud pump support 2 includes two opposing support side plates 2-1. The bottom edge of the support side plate 2-1 is welded and fixed to the inner edge of the base plate 1-1, and the inner side of the reinforcing housing 1-4 is welded and fixed to the support side plate 2-1. Therefore, the function of setting the reinforcing housing 1-4 is to increase the structural strength of both the mud pump base 1 and the mud pump support 2, thereby enhancing the overall structural strength.

[0027] An internal connecting plate 2-4 is welded between the interiors of the two support side plates 2-1. An internal front fixing plate 2-5 is welded to the front of the internal connecting plate 2-4 and an internal rear fixing plate 2-6 is welded to the rear. A front baffle 2-3 is welded to the front of the two support side plates 2-1 and a front fixing plate 2-13 is welded to the inside of the front baffle 2-3.

[0028] It also includes a mud pump support 3. The shaft support 7 of the mud pump 8 is bolted to the mud pump support 3. The bottom of the mud pump support 3 is fitted into the mud pump support 2.

[0029] In this embodiment, a transversely penetrating central pin hole 2-2 is provided in the middle of the two support side plates 2-1 and the inner front fixing plate 2-5; a transversely penetrating rear pin hole 2-7 is provided in the rear of the two support side plates 2-1 and the inner rear fixing plate 2-6; and a transversely penetrating front pin hole is provided in the front fixing plate 2-13. Correspondingly, three sets of transversely penetrating front, middle, and rear pin holes are provided at corresponding positions on the bottom of the mud pump support 3. After the bottom of the mud pump support 3 is fitted into the top of the mud pump support 2, a positioning pin is installed in each set of pin holes. Each positioning pin connects the mud pump support 3 and the mud pump support 2 into a whole. Because the mud pump support 2 and the mud pump bracket 3 can be machined with high precision, when the bottom of the mud pump bracket 3 is fitted downwards into the top of the mud pump support 2, the pin holes can be aligned laterally by relying on the dimensional adaptation of the contours. Then, the front positioning pin, the middle positioning pin and the rear positioning pin are inserted to complete the accurate installation of the mud pump assembly onto this mounting base.

[0030] In this embodiment, a positioning assembly is installed between the tops of the two support side plates 2-1. The positioning assembly includes a high-position support base 2-8 fixed to the two support side plates 2-1. Two positioning blocks 2-9 with positioning grooves 2-11 are installed on the high-position support base 2-8. A connecting block 2-10 is installed and fixed between the two positioning blocks 2-9. A horizontally penetrating pin hole is provided on the two positioning blocks 2-9. After the mud pump support base 3 is fitted and assembled with the mud pump support base 2, the two positioning protrusions on the pump casing of the mud pump 8 fall into the two positioning grooves 2-11 of the positioning assembly. Then, a pin is inserted into the pin hole, thus fixing the pump casing of the mud pump 8 to the positioning assembly of this mounting base as one unit. This not only ensures the accuracy of the installation position of the mud pump assembly, but also improves the structural strength of the mud pump assembly to a certain extent.

[0031] In this embodiment, a rear connecting plate 2-12 is welded between the rear edges of the two support side plates 2-1, and the two side edges of the rear connecting plate 2-12 are welded to the rear edges of the two support side plates 2-1. The rear connecting plate 2-12 combines the left and right support side plates 2-1 into one unit, improving the overall structural strength of the mud pump support 2.

[0032] In this embodiment, a portal-shaped front support plate 1-6 is welded between the front parts of the two base plates 1-1 of the mud pump base 1. The front baffle 2-3 of the mud pump support 2 is fixedly connected to the front support plate 1-6. The connection can be made by bolts or by welding, which can improve the overall structural strength.

[0033] In this embodiment, assembly holes are provided at the front and rear ends of the two base plates 1-1 of the mud pump base 1. A front cover plate 1-7, which is welded to the outer base plate 1-3 and the support side plate 2-1, is provided above the front assembly hole. A rear cover plate 1-8, which is welded to the outer base plate 1-3 and the support side plate 2-1, is provided above the rear assembly hole. The mud pump base 1 is fixedly connected to the cable tray using high-strength bolts located in the aforementioned assembly holes. The front cover plate 1-7 and the rear cover plate 1-8 respectively cover the front bolts and the rear bolts.

[0034] The mud pump base 1 can also be fixedly connected to the cable tray in another way, such as... Figure 2 and Figure 3 As shown, mounting pin holes 1-2 are provided at the front and rear ends of the outer base plate 1-3 of the mud pump base 1. Correspondingly, mounting pin holes 1-2 are also provided at the corresponding positions at the front and rear of the inner support side plate 2-1. This allows the mounting beam on the bridge to pass through the middle of the mud pump base 1, that is, through the two support side plates 2-1. Then, a connecting pin is inserted into the mounting pin hole 1-2 and the pin hole located on the aforementioned mounting beam.
