Description

Technical Field

[0001] The utility model belongs to the field of attached scaffolding, and in particular relates to an auxiliary installation device for a scaffolding safety net. Background Art

[0002] During the construction of high-rise buildings, scaffolding needs to be set up outside the main structure, and safety nets or protective nets need to be installed outside the scaffolding to prevent people or objects from falling or to reduce injuries caused by falling objects.

[0003] For the conventional operation of installing a protective net or a safety net, two people are generally required to do it at the same time. The specific operation process is: first install it on the bottom crossbar with two fasteners, then vertically clamp the bottom of the safety net in the fasteners, then adjust the position of the safety net, then one person holds the safety net, and the other tightens the fasteners at the bottom, and finally, the fasteners are used to strengthen the connection on the upper part of the safety net, so that the safety net is firmly fixed on the crossbar of the scaffolding. It can be seen that the installation process of the safety net is slightly complicated, and the manpower requirements are relatively large, and there is room for optimization and improvement.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0023] like Figure 1 As shown: an auxiliary installation device for a scaffold safety net, comprising a pole holder 1, a swing arm mechanism 2 and a safety net clamp 3; the pole holder 1 is used to be clamped on the pole of the scaffold, and the safety net clamp 3 is connected to the pole holder 1 through the swing arm mechanism 2.

[0024] The safety net clamp 3 includes a swing frame 3.2 and two clamping rollers 3.1 arranged side by side laterally. The two clamping rollers 3.1 are installed on the swing frame 3.2. The swing frame 3.2 is connected to the vertical pole holder 1. A safety net accommodating space is formed between the two clamping rollers 3.1. The safety net can be confined between the two clamping rollers 3.1. The safety net clamp 3 clamps the safety net through the two clamping rollers 3.1. The swing arm mechanism 2 is used to control the swing of the safety net clamp 3 to move the safety net clamp 3 out of the safety net.

[0025] like Figure 4 As shown: the surface of the clamping roller 3.1 is covered with rubber, and a magnetic strip 10 is arranged axially on the clamping roller 3.1, and the magnetic strip 10 protrudes relative to the rubber surface. The safety net is inserted between the two clamping rollers 3.1, and the distance between the two clamping rollers 3.1 is slightly smaller than the thickness of the safety net, so that a certain clamping force exists between the safety net and the two clamping rollers 3.1. When the safety net falls, the clamping roller 3.1 will be rotated until the two magnetic strips 10 generate adsorption force, which plays a role in firmly connecting the safety net.

[0026] like Figure 2 , Figure 3As shown: the swing arm mechanism 2 includes a support arm 2.1, a limit plate 2.2 and a handle 2.3, the limit plate 2.2 is vertically connected to one end of the support arm 2.1 in the length direction, and the limit plate 2.2 is connected to the vertical rod holder 1 through the support shaft 4.

[0027] The handle 2.3 is connected to the limit plate 2.2 and extends radially along the support shaft 4; the safety net clamp 3 is connected to the side of the support arm 2.1 away from the limit plate 2.2, and the force arm directions of the safety net clamp 3 and the handle 2.3 relative to the support arm 2.1 are opposite; the limit plate 2.2 is pried by the handle 2.3 to swing around the support shaft 4.

[0028] A locking mechanism 5 is connected between the swing arm mechanism 2 and the vertical pole holder 1. When the swing arm mechanism 2 rotates to the safety net clamp 3 in a horizontal position, the locking mechanism 5 can lock the swing arm mechanism 2. At this time, the safety net installed in a vertical position can be inserted between the two clamping rollers 3.1 of the safety net clamp 3.

[0029] When installing the safety net, the installation auxiliary device is fixed to the vertical pole of the scaffold through the vertical pole clamping seat 1, and then the safety net to be installed is inserted between the two clamping rollers 3.1 of the safety net clamping device 3. The installation auxiliary device assists in clamping the safety net, and one person can install the fasteners on the safety net.

[0030] After the position of the safety net relative to the scaffolding is adjusted and fastened with fasteners, the safety net clamp 3 can be rotated to leave the safety net, and the safety net clamp 3 can be flipped by turning the handle 2.3. The force applied to the safety net clamp 3 by the handle 2.3 is greater than the holding force of the two clamping rollers 3.1 on the safety net.

[0031] The locking mechanism 5 includes a baffle 5.1 and a baffle rod 5.2, one end of the baffle 5.1 is hinged to the vertical pole holder 1, and the other end is connected to the baffle rod 5.2; the baffle rod 5.2 is threadedly screwed with the baffle 5.1; the hinge axis of the baffle 5.1 is perpendicular to the support axis 4, and the baffle 5.1 swings between the locking mechanism 5 and the swing arm mechanism 2. When the safety net clamp 3 is in a horizontal posture, the top surface of the limit plate 2.2 is flush with the bottom surface of the baffle 5.1, and the baffle 5.1 rotates to the top of the limit plate 2.2 to limit the rotation of the swing arm mechanism 2, and the baffle rod 5.2 is screwed downward and stopped at the limit plate 2.2. The baffle rod 5.2 is located in the angle between the limit plate 2.2 and the support arm 2.1, limiting the baffle 5.1 from coming out.

[0032] The safety net clamp 3 is hinged to the support arm 2.1, a worm gear 6 is connected to the hinge shaft of the safety net clamp 3, a worm 7 is connected to the support arm 2.1, one end of the worm 7 passes through the limit plate 2.2, and the other end passes through the side plate 2.4 on the support arm 2.1, the worm 7 is meshed with the worm gear 6, and one end of the worm 7 passes through the limit plate 2.2 and is connected to a handwheel 8.

[0033] If the installation posture of the safety net is not in a vertical state, the angle of the safety net clamp 3 can be adjusted. The worm 7 can be driven to rotate by turning the hand wheel 8, and then the worm 7 drives the worm wheel 6 to rotate. The worm wheel 6 drives the safety net clamp 3 to flip through the hinge shaft, so that the inclination angle of the safety net clamp 3 corresponds to the installation posture of the safety net. The self-locking characteristics of the worm wheel and worm enable the inclination angle of the safety net clamp 3 to remain fixed after adjustment.

[0034] The vertical pole holder 1 comprises a U-shaped bracket 1.1, and the outer sides of the two straight plates of the U-shaped bracket 1.1 are connected with an insert plate 1.3 through a spring sheet 1.2. The spring sheet 1.2 pushes the insert plate 1.3 into the U-shaped opening through the socket on the U-shaped bracket 1.1. The insert plate 1.3 and the U-shaped bottom of the U-shaped bracket 1.1 form a space for accommodating the vertical pole. The insert plate 1.3 and the U-shaped bracket 1.1 cooperate to clamp the vertical pole, and the impact side of the insert plate 1.3 is provided with a chamfer; a buckle plate 9 is hinged on one of the straight plates of the U-shaped bracket 1.1, and a snap-in 1.4 corresponding to the hook of the buckle plate 9 is provided on the other straight plate of the U-shaped bracket 1.1. The buckle plate 9 is snapped with the snap-in 1.4 to tighten the opening of the U-shaped opening of the U-shaped bracket 1.1. The spring sheet 1.2 is arched relative to the straight plate of the U-shaped bracket 1.1, so that a pulling force is applied to the spring sheet 1.2 to pull the plug 1.3 out of the socket of the U-shaped bracket 1.1 and remove the U-shaped bracket 1.1 from the vertical pole of the scaffold.

[0035] Before installing the safety net, use the U-shaped bracket 1.1 to clamp the pole holder 1 to the pole on one side of the scaffolding, the hook of the buckle plate 9 on the pole holder 1 is buckled into the slot 1.4 on the U-shaped bracket 1.1, the opening of the U-shaped mouth of the U-shaped bracket 1.1 is tightened, and the U-shaped bracket 1.1 clamps the pole.
