Description

Technical Field

[0001] This utility model belongs to the technical field of construction safety equipment, and in particular relates to a mobile protective net frame for construction. Background Technology

[0002] In the field of construction safety equipment, traditional protective netting generally adopts a fixed installation structure, which needs to be connected to the ground or the main building by bolts or welding. Although this design can provide basic protection, it has significant limitations in actual use: its installation and dismantling process requires a lot of manpower and resources, and it is difficult to achieve rapid relocation; due to the constraints of the fixed structure, it is impossible to adjust the protection range according to the construction progress or changes in the work area. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a mobile protective net frame for construction, which effectively achieves rapid movement, improves convenience, and ensures protective effect.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a mobile protective net frame for construction, characterized in that: it includes a frame body, on which several layers of protective netting are provided; the frame body includes multiple columns evenly distributed around the circumference of the netting; each column has a movable wheel at its bottom; each movable wheel includes a mounting frame mounted on the column, a rotating frame rotatably mounted on the mounting frame, a wheel frame on one side of the rotating frame, and a wheel rotatably mounted on the wheel frame; the rotating frame is at least partially inserted into the wheel frame, and rotating columns are provided at both ends of the rotating frame; rotating grooves are formed on the inner walls of both sides of the wheel frame, and the rotating columns are at least partially inserted into the... Inside the rotating groove, a torsion spring is provided, with its two ends fixed to the rotating column and the groove wall, respectively. The mounting frame has a pin with a conical bottom. When the mounting frame is subjected to pressure and impact, it can rotate the rotating frame relative to the wheel frame, allowing the pin to be inserted into the ground. Through the pin and the connection structure between the wheel frame and the rotating frame, the protective net frame ensures that, in the event of an incident, the impact force is converted into a compressive force on the pin, inserting it into the ground to restrict movement. This ensures both the ease of wheel movement and the stability of the protective net frame in the event of an incident, guaranteeing reliable protection.

[0005] Preferably, the insertion post is rotatably connected to the mounting bracket, and its bottom is provided with a conical tip. There is a preset movement gap between the conical tip and the ground. The end of the conical tip away from the tip is provided with a stop. When the insertion post moves downward for a certain distance, the stop will contact the ground to prevent the insertion post from continuing to move.

[0006] Preferably, the outer wall of the cone tip is provided with a spiral groove around its axial direction.

[0007] Preferably, when the mounting bracket moves down to a certain stroke, the mounting bracket will squeeze and interfere with the wheel frame.

[0008] Preferably, the wheel body includes an axle, a hub disposed on the axle, and an outer wheel body covering the hub. A central groove is provided in the center of the hub, the axle passes through the central groove, and its two ends are rotatably connected to the wheel frame. A support spring is provided in the hub, and multiple support springs are provided around the circumference of the axle. The two ends of the support springs are respectively pressed and fixed to the axle wall and the central groove wall.

[0009] Preferably, one end of the axle extends out of the wheel frame and is provided with a top pressure platform, and the other end extends out of the wheel frame and is threadedly engaged with an internal threaded component. When the internal threaded component is turned to its limit stroke, the top pressure platform and the internal threaded component can press against the outer wall of the wheel frame to restrict the rotation of the axle.

[0010] Preferably, the outer wheel body is a rubber wheel body.

[0011] Preferably, the outer wheel body is provided with friction grooves.

[0012] Preferably, the mounting bracket includes a connecting plate connected to the column and a rotating plate connected to the connecting plate via a connecting spring. A buffer spring is provided between the connecting plate and the rotating plate, and both ends of the buffer spring are fixedly connected to the connecting plate and the rotating plate.

[0013] Preferably, the frame is pre-drilled with mounting holes for installing anchor bolts; so that when it is necessary to work in a single area for a long time, the grid frame can be fixedly connected to the ground by anchor bolts, thereby improving work safety in specific work scenarios.

[0014] The technical advantages of this utility model are as follows: By setting up the connection structure of the insert post, wheel frame and rotating frame, the protective net frame can ensure that in the event of an incident, the impact force is converted into the squeezing force on the insert post, and the insert post is inserted into the ground to restrict the movement of the protective net frame. Thus, while ensuring the convenience of the wheel body movement, it ensures that the protective net frame will not move in the event of an incident. At the same time, the elastic element realizes the buffer absorption of the impact, ensuring the reliability of the protection. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] like Figures 1-7 As shown, a mobile construction safety net frame includes a frame body 1, on which a safety net body 11 is installed. The safety net frame has a double-layer structure. The frame body 1 is existing technology and includes four uprights 13. The uprights 13 are distributed at the four corners and are connected and fixed to each other by horizontal bars 121 and diagonal bars 122. The horizontal bars 121 can be pre-drilled with mounting holes 14, and the anchor rods can be inserted into the mounting holes 14 to fix the frame body 1 to the ground.

[0025] Furthermore, each column 13 is equipped with a movable wheel 2 at its bottom. The movable wheel 2 includes a mounting frame, which is a double-layer structure consisting of a connecting plate 21 and a rotating plate 22. The connecting plate 21 is fixedly installed at the bottom of the column 13, and the rotating plate 22 is located below the connecting plate 21. A buffer spring 23 is provided between the connecting plate 21 and the rotating plate 22, and the two ends of the buffer spring 23 are respectively fixed to the connecting plate 21 and the rotating plate 22.

[0026] Furthermore, the rotating plate 22 has a rotatable insert post 24. The top area of ​​the insert post 24 is provided with a lower rotating support part, and the lower rotating support part is provided with a rotating guide ring. The bottom of the rotating plate 22 is provided with an upper rotating support part, and the upper rotating support part is also provided with a rotating guide ring. The rotating guide ring is a prior art technology used to support the rotation of the rotating frame 3. The rotating frame 3 is rotatably sleeved on the insert post 24 and located between the upper rotating support part and the lower rotating support part, and is rotated and supported by the rotating guide ring.

[0027] Furthermore, the bottom of the insertion post 24 is provided with a conical tip 241. A pre-set movement gap is established between the conical tip 241 and the ground in the initial state of the wheel. A stop 25 is provided at the end of the conical tip 241 away from the tip. When the insertion post 24 moves downwards a certain distance, it will partially insert into the ground. At this time, the stop 25 will contact the ground to prevent the insertion post 24 from continuing to move. A spiral groove is provided along the axis on the side wall of the insertion post 24.

[0028] Furthermore, a wheel frame 31 is rotatably mounted on one side of the mounting frame, and a wheel is rotatably mounted on the wheel frame 31. One end of the rotating frame 3 is inserted into the wheel frame 31, and rotating columns 33 are provided at both ends. Rotating grooves 4 are opened on the inner walls of both sides of the wheel frame 31, and the rotating columns 33 are inserted into the rotating grooves 4. Torsion springs 35 are provided in the rotating grooves 4, and the two ends of the torsion springs 35 are respectively fixed to the rotating columns 33 and the groove walls of the rotating grooves 4. When the mounting frame is squeezed and impacted and moves downward, it can drive the rotating frame 3 to rotate relative to the wheel frame 31 against the elastic force of the torsion springs 35, and at the same time, it will also drive the insert 24 to generate a squeezing force to insert into the ground.

[0029] Furthermore, when the mounting bracket moves down to a certain stroke, the connecting plate 21 will squeeze and interfere with the wheel frame 31, generating pressure on the wheel frame 31.

[0030] Furthermore, the wheel body includes an axle 321, a hub 322, and an outer wheel body 333. Both ends of the axle 321 are rotatably connected to the wheel frame 31. One end of the axle 321 extends beyond the wheel frame 31 and is provided with a pressure plate 3211; the other end extends beyond the wheel frame 31 and is threadedly engaged with a nut 3212. When the nut 3212 is turned to its limit stroke, the pressure plate 3211 and the nut 3212 can press against the outer wall of the wheel frame 31 to restrict the rotation of the axle 321. The axle 321 can be selected as a structure similar to an existing bolt, and the nut 3212 can also be selected as a convenient hand-tightening nut 3212 structure, which can be rotated by foot.

[0031] Furthermore, the hub 322 is mounted on the axle 321, and a central groove 36 is provided in its center. The axle 321 passes through the central groove 36. A support spring 37 is provided in the central groove 36. Multiple support springs 37 are provided around the circumference of the axle 321. The two ends of the support spring 37 are respectively pressed and fixed to the shaft wall of the axle 321 and the groove wall of the central groove 36.

[0032] Furthermore, the outer wheel body 333 covers the hub 322, and it is an existing rubber wheel body with friction grooves 38 on its outer wall along the circumferential direction.

[0033] Move the protective net frame to a suitable position. If it is only a short-term operation, tighten the nuts 3212 on the wheels. If it is a long-term operation, it can be fixed with anchor bolts. In the event of a fall, the human body will impact the net surface and squeeze the mounting frame, generating a downward impact. The insert post 24 will be at least partially inserted into the ground, and at the same time, it will squeeze the wheels. The eccentric self-locking will restrict the movement of the wheels. In addition, the buffer spring 23 will absorb the additional impact force, thereby ensuring the stability and reliability of the protective net frame.

[0034] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
