Description

[Technical Field]

[0001] This utility model relates to the field of bearing housings, specifically to a water-cooled bearing housing water pressure testing bench. [Background Technology]

[0002] Slewing bearing housings are large and extra-large bearing housings with special construction that can withstand comprehensive loads. They are characterized by their compact structure, sensitive rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The internal support point of the bearing is the shaft, and the external support is the bearing housing. There are many types of bearing housings, including water-cooled bearing housings. When testing water-cooled bearing housings, a hydrostatic testing bench is required.

[0003] Traditional water-cooled bearing housing testing stations can typically only test a single bearing housing, resulting in low testing efficiency in actual use. They cannot quickly test multiple water-cooled bearing housings. Furthermore, the water-cooled bearing housings may shift due to vibrations from the water pump during testing, potentially preventing them from performing the testing correctly and leading to poor equipment stability.

[0004] To address this, a water-cooled bearing housing hydrostatic testing bench is proposed. [Utility Model Content]

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a water-cooled bearing housing water pressure testing bench.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a water-cooled bearing housing hydrostatic testing bench, comprising:

[0007] The detection assembly includes a detection platform, a water pump fixedly installed on the top left side of the detection platform, the input end of the water pump being connected to a first flexible hose, a water tank placed at the bottom of the detection platform, the first flexible hose extending into the inner cavity of the water tank, the output end of the water pump being connected to a second flexible hose, a first bearing body placed on the top right side of the detection platform, a second bearing body placed on the top right side of the detection platform, the other end of the second flexible hose being connected to the inner cavity of the first bearing body, a third flexible hose connected to the bottom of the first bearing body, the other end of the third flexible hose being connected to the inner cavity of the second bearing body, and a pressure sensor fixedly installed at the input end of the water pump.

[0008] A fixing component includes two positioning pins, both of which are fixedly installed on the top of the detection component. Each positioning pin is movably connected to a movable block, and the surface of the movable block is provided with an adjustment groove. Each detection component has a column fixedly installed on its top, and a fixing bolt is fixedly installed on the top of each column. The fixing bolt passes through the adjustment groove and extends to the top of the movable block. A nut is threaded onto the surface of the fixing bolt. A pressing block is fixedly installed on the bottom of each movable block, and both pressing blocks are fitted against the surfaces of the nut and the pressing block.

[0009] The water-cooled bearing housing water pressure test bench of this utility model is further configured such that: a base plate is fixedly installed on both the left and right sides of the bottom of the test bench, and the surface of the base plate is threaded with anchor bolts.

[0010] The water-cooled bearing housing water pressure test bench of this utility model is further configured such that: a first slot is opened on the top of the test bench, and the first hose passes through the first slot and extends to the bottom of the test bench.

[0011] The water-cooled bearing housing water pressure test bench of this utility model is further configured such that: a second slot is opened at the top of the test bench, and the second hose passes through the second slot and extends to the bottom of the test bench.

[0012] The water-cooled bearing housing hydrostatic test bench of this utility model is further configured such that: a gasket is fitted on the surface of the fixing bolt, the bottom of the gasket is in contact with the top of the moving block, and the top of the gasket is in contact with the bottom of the nut.

[0013] The water-cooled bearing housing water pressure test bench of this utility model is further configured such that: the bottom of the lower pressure block is arc-shaped, and the material of the lower pressure block is rubber.

[0014] Compared with the prior art, this utility model has the following beneficial effects: First, by setting up a detection component, the output of the water pump enables the second and third hoses to cooperate in injecting water from the water tank into the inner cavity of the first and second bearing bodies. When the pressure sensor detects that the injected pressure has increased, it stops the output of the water pump. At this time, the inner cavity of the first and second bearing bodies is full, which makes it easy to observe whether there is any leakage on the surface of the first and second bearing bodies, and realizes the detection work of the first and second bearing bodies. This method can realize the simultaneous detection of multiple water-cooled bearing seats, improves the convenience and flexibility of water-cooled bearing seat detection, and has low cost, making it suitable for promotion.

[0015] II. This utility model, by setting a fixing component, causes the moving block to move downwards through the rotation and pressing of the nut. When the moving block moves, it drives the pressing block to move downwards synchronously, so that the pressing block presses down and fixes the second bearing body and the first bearing body. This effectively avoids the displacement of the second bearing body and the first bearing body due to the vibration of the water pump during the testing process, ensuring the stability of the second bearing body and the first bearing body during testing, and making it convenient for operators to use.

Detailed Implementation Methods

[0021] The present invention will be further described in detail below through specific embodiments.

[0022] Example 1

[0023] like Figure 1-4 As shown, this utility model embodiment provides a water-cooled bearing housing hydrostatic testing bench, including:

[0024] The testing component 1 includes a testing platform 101. A water pump 102 is fixedly installed on the top left side of the testing platform 101. The input end of the water pump 102 is connected to a first flexible hose 103. A water tank 104 is placed at the bottom of the testing platform 101. The first flexible hose 103 extends into the inner cavity of the water tank 104. The output end of the water pump 102 is connected to a second flexible hose 105. A first bearing body 106 and a second bearing body 107 are placed on the top right side of the testing platform 101. The other end of the second flexible hose 105 is connected to the inner cavity of the first bearing body 106. The bottom of the first bearing body 106... A third flexible hose 108 is connected, and the other end of the third flexible hose 108 is connected to the inner cavity of the second bearing body 107. A pressure sensor 109 is fixedly installed at the input end of the water pump 102. A base plate 110 is fixedly installed on both the left and right sides of the bottom of the test platform 101. Anchor bolts 111 are threaded onto the surface of the base plate 110. A first slot 112 is opened at the top of the test platform 101. A first flexible hose 103 passes through the first slot 112 and extends to the bottom of the test platform 101. A second slot 113 is opened at the top of the test platform 101. A second flexible hose 105 passes through the second slot 113 and extends to the bottom of the test platform 101.

[0025] By setting up the detection component 1, the output of the water pump 102 causes the second hose 105 and the third hose 108 to cooperate in injecting water from the water tank 104 into the inner cavity of the first bearing body 106 and the second bearing body 107. When the pressure sensor 109 detects that the injected pressure has increased, it stops the output of the water pump 102. At this time, the inner cavity of the first bearing body 106 and the second bearing body 107 is full, which makes it easy to observe whether there is any leakage on the surface of the first bearing body 106 and the second bearing body 107, and realizes the detection work of the first bearing body 106 and the second bearing body 107. This method can realize the simultaneous detection of multiple water-cooled bearing housings, improves the convenience and flexibility of water-cooled bearing housing detection, and has low cost, making it suitable for promotion.

[0026] Example 2

[0027] like Figure 1 , Figure 2 and Figure 4As shown, in one embodiment, the fixing component 2 includes positioning pins 201, both of which are fixedly installed on the top of the detection component 1. The positioning pins 201 are movably connected to a moving block 202. An adjustment groove 203 is provided on the surface of the moving block 202. A column 204 is fixedly installed on the top of the detection component 1. A fixing bolt 205 is fixedly installed on the top of the column 204. The fixing bolt 205 passes through the adjustment groove 203 and extends to the top of the moving block 202. A nut 206 is threaded onto the surface of the fixing bolt 205. A pressing block 207 is fixedly installed on the bottom of the moving block 202. Both pressing blocks 207 are attached to the surfaces of the nut 206 and the pressing block 207. A washer 208 is sleeved on the surface of the fixing bolt 205. The bottom of the washer 208 contacts the top of the moving block 202, and the top of the washer 208 contacts the bottom of the nut 206. The bottom of the pressing block 207 is arc-shaped and made of rubber.

[0028] By setting the fixing component 2, the moving block 202 moves downwards due to the rotation and pressing of the nut 206. When the moving block 202 moves, it drives the pressing block 207 to move downwards synchronously, so that the pressing block 207 presses down and fixes the second bearing body 107 and the first bearing body 106. This effectively avoids the displacement of the second bearing body 107 and the first bearing body 106 due to the vibration of the water pump 102 during the testing process, ensuring the stability of the second bearing body 107 and the first bearing body 106 during testing and making it convenient for operators to use.

[0029] In operation, the present invention works as follows: First, the second bearing body 107 and the first bearing body 106 are placed on the top of the testing platform 101. Then, the nut 206 is threaded onto the surface of the fixing bolt 205. When the nut 206 moves downward, it squeezes the moving block 202. At this time, the moving block 202 simultaneously drives the pressing block 207 to move downward. The pressing block 207 presses down and fixes the second bearing body 107 and the first bearing body 106, thus fixing the second bearing body 107 and the first bearing body 106. Then, the water pump 102 pumps water from the inner cavity of the water tank 104 through the first hose 103. Water is then injected into the inner cavity of the first bearing body 106 through the second hose 105. At this time, the water in the inner cavity of the first bearing body 106 can be injected into the inner cavity of the second bearing body 107 through the third hose 108. When the pressure sensor 109 detects that the injected pressure has reached the required level, the output of the water pump 102 is stopped. At this time, the inner cavities of the second bearing body 107 and the first bearing body 106 are full of water. Then, the surfaces of the second bearing body 107 and the first bearing body 106 are observed for any leakage, thus enabling the detection of the second bearing body 107 and the first bearing body 106.

[0030] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
