The above-mentioned solution solves the problem that the size of the round steel support ring of the existing manhole cover compression test detection device is fixed and can only detect stainless steel manhole covers of the same size. When detecting stainless steel manhole covers of different sizes, the detection device needs to be replaced, which leads to inconvenience in use.

[0022] According to this specific embodiment, the limit bearing circular groove 102 is set at the top of the inverted V-shaped support 101.

The limiting card 111 is fixedly connected to the connecting block 110 and is located on the side of the connecting block 110 away from the second spring 109. The detection mechanism 112 is set on one side of the inverted V-shaped support 101. When the stainless steel manhole cover needs to be tested for compressive load after production, the worker first checks the size of the manhole cover. The staff moves the two guide blocks 107 toward each other and compresses the first spring 108. At this time, the manhole cover is placed into the limit bearing circular groove 102 along the inclined plate 104. After the placement is completed, the staff releases the guide block 107, and the first spring 108 is reset, pushing the two guide blocks 107 to move in opposite directions on the guide rod 106, so that the limit card plate 111 can contact the manhole cover. When the limit card plate 111 contacts the manhole cover, the first spring 108 continues to stretch, so that the second spring 109 between the guide block 107 and the connecting block 110 is compressed, so that the limit card plate 111 The plate 111 can resist the stainless steel manhole cover, fix the manhole cover in the limit load circular groove 102, and test the compressive bearing performance of the manhole cover through the detection mechanism 112.

After the manhole cover is fixed, the safety grating 119 is used to detect whether the staff has entered the test area of ​​the support frame 113. If the staff or other personnel accidentally enter the detection area, an alarm can be issued to the detection device control terminal, thereby triggering the detection device to stop operating or other safety measures. When the manhole cover is damaged during detection, the baffle 120 can prevent the damaged manhole cover fragments from splashing out of the detection area of ​​the support frame 113.

[0027] At the same time, the hydraulic cylinder 121 is fixedly connected to the mounting frame 117 and is located on one side of the mounting frame 117.

[0028] The utility model provides a compression load-bearing detection device for a stainless steel manhole cover. When the stainless steel manhole cover needs to be tested for compression load-bearing after production, the staff first moves the two guide blocks 107 toward each other according to the size of the manhole cover and compresses the first spring 108. At this time, the manhole cover is placed into the limit load circular groove 102 along the inclined plate 104. After placement is completed, the staff releases the guide blocks 107, and the first spring 108 resets, pushing the two guide blocks 107 to move in opposite directions on the guide rod 106, so that the limit card 111 can contact the manhole cover. When the limit card 111 contacts the manhole cover, the first spring 108 continues to stretch, so that the second spring 109 between the guide block 107 and the connecting block 110 is compressed, so that the limit card 111 can press against the stainless steel manhole cover, fixing the position of the manhole cover. After the installation and fixation of the manhole cover is completed By starting the hydraulic cylinder 121, the output end of the hydraulic cylinder 121 pushes the impact head 122 down, so that the impact head 122 hits the manhole cover, and the pressure indicator provided on the hydraulic cylinder 121 displays the pressure on the manhole cover. At the same time, the safety grating 119 detects whether the staff has entered the test area of ​​the support frame 113. If the staff or other personnel accidentally enter the detection area, an alarm can be sent to the detection device control terminal, thereby triggering the detection device to stop operating or other safety measures. When the manhole cover is damaged during detection, the baffle 120 can prevent the damaged manhole cover fragments from splashing out of the detection area of ​​the support frame 113, thereby solving the problem that the size of the round steel support ring of the existing manhole cover pressure test detection device is fixed and can only detect stainless steel manhole covers of the same size. When detecting stainless steel manhole covers of different sizes, the detection device needs to be replaced, which makes it inconvenient to use.
