[0017] 4. The two opening clamping plates of the present invention can cooperate to arrange and limit the wires connecting the host, preventing the wires from winding around each other. The shock-absorbing ring can perform shock absorption in the front-back direction on the placement frame, thereby further protecting the host in the placement frame from shock.

[0018] 5. The mounting plate of the present invention can be installed with a display used in cooperation with the host, and the position of the mounting plate is adjustable, so as to facilitate the adjustment of the position of the display and facilitate use. BRIEF DESCRIPTION OF THE DRAWINGS

The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that the terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation mode.

[0030] Embodiment 1

[0031] Combined with Figure 1-2 As shown, the present application provides a shock-proof device for the main body of a tower crane monitoring system, which includes a support 1, a cylinder block 2, a piston rod 3, a first spring 5, a placement frame 6, a buffer assembly 7 and a shielding assembly 8. The top of the support 1 is symmetrically connected with cylinder blocks 2 on the left and right. The tops of the two cylinder blocks 2 are both slidably connected with piston rods 3. Air outlet holes 4 are opened in the middle of the bottoms of the two cylinder blocks 2. The air outlet holes 4 are used to discharge the gas in the cylinder blocks 2. A placement frame 6 is connected between the tops of the two piston rods 3. The placement frame 6 is used to place the main body of the tower crane monitoring system. First springs 5 are connected between the bottoms of the two piston rods 3 and the inner bottoms of the two cylinder blocks 2 respectively. The first springs 5 are used to shock-absorb and protect the main body in the placement frame 6. A buffer assembly 7 is arranged between the support 1 and the placement frame 6. The buffer assembly 7 is used to buffer the placement frame 6, so as to further shock-absorb and protect the main body in the placement frame 6. A shielding assembly 8 is arranged on the top of the placement frame 6. The shielding assembly 8 is used to shield the main body in the placement frame 6 to prevent the main body from falling out of the placement frame 6.

[0032] Combined with Figure 3As shown, the buffer assembly 7 includes a guide sleeve 71, a shielding plate 72, a connecting plate 73, a vertical rod 74 and a cable 75. The guide sleeves 71 are symmetrically connected to the left and right of the lower part of the bracket. The shielding plates 72 are slidably connected in the two guide sleeves 71. The connecting plates 73 are hinged to the inner sides of the two shielding plates 72. The cable 75 is connected to the middle of the bottom of the placement frame 6. The bottom end of the cable 75 is connected to the vertical rod 74. The lower part of the vertical rod 74 is hinged to the two connecting plates 73.

[0033] Combined with Figure 4 As shown, the shielding assembly 8 includes a guide rod 81, a protection plate 82 and a limit ring 83. The guide rods 81 are symmetrically connected to the left and right of the rear side of the top of the placement frame 6. The protection plate 82 is slidably connected between the two guide rods 81. The protection plate 82 is used to shield the host in the placement frame 6 to prevent the host from falling out of the placement frame 6. The upper parts of the two guide rods 81 are both connected with limit rings 83. The limit rings 83 are used to limit the protection plate 82 to prevent the protection plate 82 from moving upward excessively.

[0034] First, install this device at a suitable position on the tower crane. Then, place the main unit, which is an important component of the tower crane monitoring system, into the placement frame 6. Subsequently, manually move the protective plate 82 upward by hand so that the protective plate 82 blocks the main unit within the placement frame 6, thus preventing the main unit from falling out of the placement frame 6. When the tower crane operates and generates vibrations, causing the placement frame 6 to vibrate and move downward, the main unit moves downward accordingly. The downward movement of the placement frame 6 pushes the piston rod 3 downward, and the first spring 5 is compressed accordingly. Since there is gas in the cylinder body 2, the piston rod 3 moves downward slowly. The downward movement of the piston rod 3 can slowly push the gas in the cylinder body 2 out through the air outlet hole 4. Thus, through the cooperation among the cylinder body 2, the piston rod 3, and the first spring 5, the placement frame 6 can move downward slowly during vibrations, thereby providing shock absorption protection for the main unit within the placement frame 6. When the placement frame 6 moves downward, the pull wire 75 is relaxed. When the placement frame 6 moves downward until it contacts the vertical rod 74, the placement frame 6 continues to move downward and pushes the vertical rod 74 downward. The downward movement of the vertical rod 74 pushes the two baffle plates 72 to move outward simultaneously through the two connecting plates 73. After the baffle plates 72 move outward, they can block a part of the air outlet hole 4. When the first spring 5 resets, it can cause the piston rod 3 to move upward. The upward movement of the piston rod 3 can draw the external gas into the cylinder body 2 through the air outlet hole 4. Since a part of the air outlet hole 4 is blocked, the piston rod 3 will move upward slowly instead of quickly. The slow upward movement of the piston rod 3 pushes the placement frame 6 to move upward slowly, and the slow upward movement of the placement frame 6 drives the main unit within it to move upward slowly, thereby providing shock absorption protection for the main unit within the placement frame 6. When the placement frame 6 moves upward until it disengages from the vertical rod 74, the placement frame 6 continues to move upward and pulls the vertical rod 74 to move upward and reset through the pull wire 75. The upward movement and reset of the vertical rod 74 pull the two baffle plates 72 to move inward simultaneously through the two connecting plates 73. After the baffle plates 72 move inward and reset, they do not block a part of the air outlet hole 4. In this way, the placement frame 6 of this device can place the main unit. After the protective plate 82 moves upward, it can block the main unit within the placement frame 6, preventing the main unit from falling out of the placement frame 6. The cooperation among the cylinder body 2, the piston rod 3, and the first spring 5 enables the placement frame 6 to move downward slowly during vibrations. When the first spring 5 resets, since a part of the air outlet hole 4 is blocked, the placement frame 6 will move upward slowly. The slow upward and downward movement of the placement frame 6 drives the main unit within it to move upward and downward slowly, thereby providing shock absorption protection for the main unit within the placement frame 6.

[0035] Embodiment 2

[0036] Based on Embodiment 1, combined with Figure 1 and Figure 5As shown in the figure, it further includes a pressing component 9. The pressing component 9 is provided at the top of the placement frame 6 and is used to press the host in the placement frame 6, thereby further preventing the host from falling out of the placement frame 6. The pressing component 9 includes a pressing block 91, a nut 92 and a lead screw 93. The lead screw 93 is rotatably connected to the front side of the top of the placement frame 6. The nut 92 is connected to the lead screw 93 by means of threading. The outer wall of the nut 92 is connected with a pressing block 91. The pressing block 91 is slidably connected to the placement frame 6. The pressing block 91 is used to press the host in the placement frame 6, thereby further preventing the host from falling out of the placement frame 6. A rubber block is connected to the bottom of the pressing block 91, which can increase the friction with the host to prevent slipping and can prevent the host from being damaged.

[0037] Manually rotate the lead screw 93 to move the nut 92 downward. The downward movement of the nut 92 drives the pressing block 91 to move downward. After the pressing block 91 moves downward, the host can be pressed and fixed in the placement frame 6, thereby further preventing the host from falling out of the placement frame 6. When there is no need to press the host, rotate the lead screw 93 in the reverse direction to make the nut 92 drive the pressing block 91 to move upward to release the host.

[0038] Embodiment 3

[0039] On the basis of Embodiment 2, in combination with Figure 1 and Figure 6 As shown in the figure, it further includes a clamping component 10. A clamping component 10 is provided between the bracket 1 and the placement frame 6. The clamping component 10 is used to clamp the protective plate 82 to prevent the protective plate 82 from detaching from the host. The clamping component 10 includes a contact shell 101, a fixed block 102, a clamping block 103 and a second spring 104. The lower part of the bracket 1 is connected with a contact shell 101. The contact shell 101 contacts the protective plate 82. Fixed blocks 102 are connected to the rear sides of the left and right sides of the placement frame 6. A clamping block 103 is slidably connected between the two fixed blocks 102. The left and right sides of the front part of the clamping block 103 are both inclined surfaces. Second springs 104 are connected between the clamping block 103 and the two fixed blocks 102. Slots for clamping with the clamping block 103 are opened on the left and right sides of the rear part of the protective plate 82.

[0040] Initially, the protective plate 82 is supported by the contact shell 101 and cannot move downward. When the placement frame 6 moves downward, it drives the fixed block 102, the clamping block 103, and the second spring 104 downward. When the clamping block 103 moves downward to contact the protective plate 82, the clamping block 103 continues to move downward and is squeezed by the protective plate 82. The clamping block 103 then moves backward, and the second spring 104 is stretched accordingly. When the clamping block 103 moves downward to align with the card slot at the rear of the protective plate 82, under the action of the reset of the second spring 104, the clamping block 103 can move forward and be inserted into the card slot at the rear of the protective plate 82. At this time, the protective plate 82 is already aligned with the main unit in the placement frame 6 and can block the main unit. Thus, when the placement frame 6 drives the fixed block 102, the clamping block 103, and the second spring 104 to move upward and reset, the clamping block 103 can drive the protective plate 82 to move upward together, and the clamping block 103 can hold the protective plate 82 in place, enabling the protective plate 82 to continuously block the main unit, thereby further preventing the main unit from falling out of the placement frame 6.

[0041] Embodiment 4

[0042] On the basis of Embodiment 3, in combination with Figure 1 and Figure 7 as shown, it further includes a limiting component 11. A limiting component 11 is provided between the contact shell 101 and the placement frame 6. The limiting component 11 is used to arrange and limit the lines connected to the main unit to prevent the lines from winding around each other. The limiting component 11 includes a fixed rod 111, a shock-absorbing ring 112, an opening clamping plate 113, and a screw rod 114. The fixed rods 111 are symmetrically connected to the left and right sides of the rear surface of the contact shell 101. The shock-absorbing rings 112 are connected to the tops of the two fixed rods 111. The shock-absorbing rings 112 are used to further protect the main unit in the placement frame 6 from shock. The opening clamping plates 113 are symmetrically placed front and back between the two fixed rods 111. Two screw rods 114 are symmetrically connected to the left and right sides between the two opening clamping plates 113 by means of threaded connection.

[0043] Unscrew the two screw rods 114 from the two opening clamping plates 113, then the height of the two opening clamping plates 113 can be adjusted. After the adjustment is completed, screw the two screw rods 114 back onto the two opening clamping plates 113, thereby fixing the two opening clamping plates 113 together and fixing the two opening clamping plates 113 on the fixed rods 111 to prevent the two opening clamping plates 113 from moving by themselves. Subsequently, pass the lines to be connected to the main unit one by one through the space between the two opening clamping plates 113, and then connect the lines to the main unit one by one. In this way, the two opening clamping plates 113 can cooperate to arrange and limit the lines connected to the main unit to prevent the lines from winding around each other. The shock-absorbing rings 112 can shock-absorb the placement frame 6 in the front-back direction, thereby further protecting the main unit in the placement frame 6 from shock.

[0044] Embodiment 5

[0045] Based on Embodiment 4, in combination with Figure 1 and Figure 8 as shown, it further includes a support assembly 12. The support assembly 12 is provided on the contact shell 101 and is used for installing a display. The support assembly 12 includes a fixing frame 121, a mounting plate 122 and fixing bolts 123. The upper side of the rear part of the contact shell 101 is connected with the fixing frame 121 by means of bolt connection. The upper part of the fixing frame 121 is slidably connected with the mounting plate 122. The mounting plate 122 is used for installing a display. The fixing bolts 123 are symmetrically connected up and down at the rear side of the mounting plate 122 by means of threaded connection. The fixing bolts 123 are used for fixing the mounting plate 122 so as to fix the position of the display.

[0046] The display used in cooperation with the host can be installed on the mounting plate 122, and the mounting plate 122 can also be moved left and right as needed, so as to adjust the position of the display. After the position adjustment of the display is completed, tighten the two fixing bolts 123 to fix the mounting plate 122, so that the display can be prevented from moving.

[0047] The above embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications, improvements and substitutions can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
