[0002] Construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. During the construction process, in order to reduce the harm to nearby pedestrians caused by construction, it is often necessary to use safety fences to protect the construction site.

[0003] The safety guardrail in the existing construction safety protection device is used at the opening for vehicles to enter and exit. When a transport vehicle passes through the opening of the safety guardrail, the transport vehicle may collide with both sides of the opening of the safety guardrail, which may cause damage to the safety guardrail. Therefore, the damaged safety guardrail needs to be replaced, which will increase the cost and make the safety guardrail unable to be reused. In view of this, we propose a construction safety protection device. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, the utility model provides a construction safety protection device, including a first protective plate 1, a cavity 10 penetrating the right end of the first protective plate 1 is opened inside the first protective plate 1, one end of the second protective plate 2 slides in the cavity 10, a movable plate 11 is slidably arranged in the cavity 10, and the movable plate 11 is located on the left side of the second protective plate 2, a plurality of second springs 12 are welded at equal intervals between the movable plate 11 and the second protective plate 2, and the number of the second springs 12 can be set according to the actual height of the second protective plate 2, and buffer mechanisms 9 are arranged at equal intervals between the movable plate 11 and the inner end of the cavity 10, and the number of the buffer mechanisms 9 can be set according to the actual height of the second protective plate 2.

[0025] The buffer mechanism 9 includes a first connecting plate 91 symmetrically welded to the moving plate 11, a first slide bar 93 is welded between the two first connecting plates 91, a second connecting plate 92 welded and fixed to the moving plate 11 is welded in the middle of the first slide bar 93, and moving blocks 94 are symmetrically slidably arranged on the first slide bar 93, and the two moving blocks 94 are respectively located in the middle between the two first connecting plates 91 and the second connecting plates 92, and first springs 95 are welded between the two first connecting plates 91 and the second connecting plate 92 and the two moving blocks 94, and the four first springs 95 are all sleeved on the outside of the first slide bar 93;

[0026] like Figure 5As shown, longitudinal grooves are symmetrically provided at the inner end of the cavity 10 of the first protective plate 1, one end of the two fixed seats 97 is respectively located in the two longitudinal grooves and realizes longitudinal sliding, and the surfaces where the longitudinal grooves and the fixed seats 97 abut are both set to smooth surfaces to reduce the friction between the devices, and at the same time, the longitudinal grooves and the fixed seats 97 are mutually limited to avoid separation from each other, and each fixed seat 97 can be specifically set as two first support plates, and the two support rods 96 are respectively rotatably set between the two first support plates through pins, and the left ends of the two moving blocks 94 are symmetrically welded with second support plates, and the other ends of the support rods 96 are rotatably set between the two second support plates through pins, and the two support rods 96 are symmetrically set to cross each other, and the intersection of the two support rods 96 is rotatably set to each other through the central axis 14;

[0027] A second slide bar 98 is slidably provided between the two moving blocks 94 and is located on the left side of the first slide bar 93. The second slide bar 98 can guide the two moving blocks 94, and combined with the first slide bar 93, the moving blocks 94 can be prevented from rotating, so that the moving blocks 94 can only slide up and down along the first slide bar 93 and the second slide bar 98, or move left and right; support rods 99 are welded on both sides of the upper and lower ends of the second slide bar 98, and a slider 910 is welded on one end of the four support rods 99 away from the second slide bar 98. Slide blocks 910 are symmetrically provided on the front and rear sides of the cavity 10. Slot 911, four sliders 910 slide in the four slide slots 911 respectively, and the slider 910 is set to a trapezoidal shape to play a role of limiting and guiding, thereby ensuring the stability of the second slide bar 98 when moving and the stability of the two support rods 96 when rotating. At the same time, the slide slot 911 can limit the moving distance of the second slide bar 98, thereby preventing the second slide bar 98 from moving a large distance toward the support rod 96, causing the two support rods 96 to rotate a larger angle, thereby causing the two moving blocks 94 to cause a larger deformation to the first spring 95 to affect the elastic force of the first spring 95.

[0028] A first column 3 is welded to the left end of the first protective plate 1, a second column 4 is welded to the right end of the second protective plate 2, a bottom plate 5 is welded to the lower end of the first column 3, the bottom plate 5 is fixed to the ground by bolts, a groove 6 is opened at the upper end of the right side of the bottom plate 5, the lower end of the second column 4 slides in the groove 6, when the second column 4 is located at the rightmost end of the groove 6, the left end of the second protective plate 2 will not slide out of the cavity 10, and the groove 6 can also prevent the second protective plate 2 from moving a large distance toward the first protective plate 1, causing the first spring 95 and the second spring 12 to produce a large deformation, thereby affecting the elastic force of the first spring 95 and the second spring 12.

[0029] The second column 4 is fixed with fixing plates 7 on the upper and lower sides of the right end by bolts. When the roller 8 is severely worn, the bolts can be removed to facilitate the replacement of the roller 8. The lower fixing plate 7 is located on the upper side of the bottom plate 5. A roller 8 is arranged between the two fixing plates 7 to rotate via a rotating shaft. When the transport vehicle collides with the protective device, it will collide with the roller 8, and the roller 8 will roll along the vehicle, thereby effectively reducing the mutual wear between the roller 8 and the vehicle, so as to avoid collision and wear on the second column 4 and the second protective plate 2, thereby increasing the number of reuses of the first protective plate 1, the second protective plate 2, the first column 3 and the second column 4.

[0030] like Figure 3 As shown, a transverse groove 13 is provided on one side of the inner wall of the cavity 10 between the two fixing seats 97, and a central shaft 14 is movably inserted into the transverse groove 13. The central shaft 14 slides in the transverse groove 13 to achieve the functions of guiding and limiting, thereby preventing the two fixing seats 97 from falling under the action of gravity. It should be noted that the length of the transverse groove 13 is greater than the length of the slide groove 911, thereby preventing the support rod 99 from sliding in the slide groove 911 due to the short length of the transverse groove 13, thereby preventing the buffering effect from being affected.

[0031] Working principle and process of this utility model:

[0032] The safety protection device is symmetrically arranged on both sides of the entrance and exit of the transport vehicle, and the second column 4 is located on both sides of the entrance and exit. When the transport vehicle passes through the entrance and exit and collides with the safety protection device, it will collide with the roller 8, and the roller 8 will roll along the vehicle. At the same time, a collision force toward the first protective plate 1 will be generated on the roller 8, so that the second protective plate 2 slides into the cavity 10, compressing the second spring 12, thereby causing the movable plate 11 to move toward the first column 3, and then causing the first slide bar 93, the movable block 94 and the second slide bar 98 to move toward the fixed seat 97, so that the ends of the two support rods 96 close to the movable block 94 are respectively moved toward each other. The two moving blocks 94 slide on the first slide bar 93 in the direction away from each other, thereby compressing the first spring 95 arranged between the first connecting plate 91 and the moving block 94, and stretching the first spring 95 arranged between the second connecting plate 92 and the moving block 94, so that the collision force of the transport vehicle on the roller 8 is absorbed by the four first springs 95, and the second spring 12 also absorbs part of the collision force.

[0033] When the force disappears, the elastic force of the four first springs 95 resets the buffer mechanism 9. At the same time, the second spring 12 and the movable plate 11 will also reset, so that the second protective plate 2, the second column 4 and the roller 8 return to their initial positions. Therefore, the second spring 12 and the buffer mechanism 9 can effectively reduce the collision effect of the vehicle on the safety protection device, thereby effectively reducing the damage caused by the vehicle to the safety protection device, so that the safety protection device can be reused.
