Description

Technical Field

[0001] The utility model belongs to the technical field of grid construction, and specifically relates to a ladder for patching plates and a grid structure. Background Art

[0002] Photovoltaic panels are usually laid on the ground and then hoisted through the reserved holes for photovoltaic panels, so it is necessary to carry out panel repair operations at sea. Since the working surface of the grid structure is smooth and has a slope, there is no place for maintenance personnel to climb or step on the surface.

[0003] In view of the above technical problems, it is necessary to set a ladder on the grid structure. The prior art discloses a utility model patent named a ladder device for grid construction (authorization announcement number: CN 213038934 U), which provides a solid foothold for grid construction personnel. Installation, disassembly and transfer can be completed by one person, which saves time and effort and has good practicality. The grid support rod of the prior art includes a connecting rod, and U-shaped heads with outward openings are respectively arranged at both ends of the connecting rod.

[0004] However, the stopper and the web of the metal structure are in direct contact, which may easily cause structural damage to the stopper and the web. Utility Model Content

[0005] The utility model aims to solve the above-mentioned technical problems existing in the prior art, and provides a ladder and a grid structure for patching plates, in which a plurality of ladder rod units of different lengths can be arranged on two webs, providing an operator with a plurality of places to climb and step, and at the same time the ladder rod units are detachable on the webs for convenient recycling and reuse, and an anti-slip sleeve is sleeved on the outer side of a limiting card plate to avoid direct contact between the limiting card plate and the webs and thus causing damage to the structure, and the anti-slip sleeve can increase the friction between the limiting card plate and the webs, and increase the stability of the ladder rod units on the webs.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The ladder for plate patching is characterized in that it comprises a plurality of ladder rod units arranged on two inclined webs, and the length of the ladder rod units along the length direction of the ladder rod units gradually decreases from top to bottom. The ladder rod units comprise a cross bar, and both ends of the cross bar are provided with a limit card plate, and the limit card plate is provided with a limit groove, and under the gravity of the ladder rod unit, the limit groove is limited on the web, and the outer side of the limit card plate is covered with an anti-slip sleeve, and the anti-slip sleeve is in contact with the outer surface of the web, and the anti-slip sleeve is used to increase the friction between the limit card plate and the web.

[0008] Furthermore, the limiting clamping plate is fixedly connected with a connecting plate, and the connecting plate and the end of the cross bar are welded and fixed, so as to avoid direct welding of the cross bar and the limiting clamping plate, which may cause damage to the limiting clamping plate structure.

[0009] Furthermore, the limit clamping plate is provided with two clamping plates, the connecting plate is arranged between the two clamping plates, and the clamping plates and the connecting plate are fixedly connected by bolts. At the same time, the limit clamping plate and the connecting plate are fixedly connected by welding. Before the limit clamping plate and the connecting plate are welded, bolts are used to fix the clamping plates and the connecting plate, so that the clamping plates and the connecting plate are accurately butted, and the connection between the limit clamping plate and the connecting plate is fully welded, improving the welding quality.

[0010] Furthermore, the anti-slip sleeve is made of a rubber sleeve or a cloth sleeve.

[0011] Furthermore, a reinforcing plate is welded between the connecting plate and the cross bar, increasing the connection strength between the connecting plate and the cross bar and preventing the connecting plate from falling off the cross bar.

[0012] Furthermore, an arc surface is provided on the inner side of the reinforcing plate, and the arc surface is attached to the outer surface of the cross bar, increasing the connection strength between the reinforcing plate and the cross bar.

[0013] Furthermore, the reinforcing plate is provided with a first through hole, and the cross bar is provided with a second through hole. Before welding the reinforcing plate, a bolt rod is passed through the first through hole and the second through hole, and then two locking nuts are screwed onto the bolt rod and tightened, so that the reinforcing plate is accurately positioned on the cross bar. Then, the connection between the reinforcing plate and the cross bar is fully welded, and the connection between the reinforcing plate and the connecting plate is fully welded, improving the welding quality.

[0014] Furthermore, the reinforcing plate is provided with a groove, and the locking nut is arranged in the groove, so that the locking nut is embedded in the reinforcing plate, playing a role in protecting the locking nut.

[0015] A grid structure, characterized in that: it includes a single spherical support at the lower part and a plurality of spherical joints at the upper part. An upper chord rod is welded between adjacent two spherical joints, a web member is welded between the spherical support and the spherical joint, and the distance between adjacent two web members gradually decreases from top to bottom. The ladder for the patch plate of the present utility model is installed on the web member.

[0016] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0017] The distance between adjacent two web members in the grid structure of the present utility model gradually decreases from top to bottom, and multiple ladder rod units with different lengths can be arranged on the two web members. The cross bar of the ladder rod unit is the force application point for the operator, providing multiple places for the operator to climb and step on.

[0018] When installing the ladder rod unit, the ladder rod unit is installed from top to bottom between the two web members. Under the action of the gravity of the ladder rod unit, the limit groove abuts against the web member. At this time, the anti-slip sleeve contacts the outer surface of the web member, avoiding direct contact between the limit clamping plate and the web member and causing damage to the structure. The anti-slip sleeve can increase the friction between the limit clamping plate and the web member, increasing the stability of the ladder rod unit on the web member.

[0019] When the ladder member unit is moved upward, the limiting groove of the limiting clamping plate disengages from the web member at this time, and it can be disassembled from the grid structure, so that the ladder member unit is detachable on the web member, which is convenient for recycling and reuse.
