Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket hoisting technology, and in particular to a photovoltaic bracket hoisting mechanism. Background Technology

[0002] In current photovoltaic power stations (ground-mounted / mountainous), considering the flatness of the ground and the ease of construction, single-column support structures are generally used; single-column supports have larger cross-sections, higher strength, and are heavier than double-column supports.

[0003] There are currently two hoisting and installation methods:

[0004] 1. Loose cargo and parts are handled manually---The triangular inclined support assembly contains many parts, including inclined beams, front inclined supports, rear inclined supports, angle steel columns, clamps, etc. The installers stand at a height and install the above parts one by one in a certain step sequence, and finally assemble them together.

[0005] 2. Equipment hoisting---The triangular inclined support assembly is pre-assembled on the ground, with only the clamp connection to the cement pile foundation remaining loose and adjustable. This triangular assembly is hoisted using excavators, truck cranes, or other crane equipment.

[0006] Manual handling presents several problems: it requires the construction of an aerial work platform, personnel need to pass the equipment upwards from the ground individually, and at least several people are needed for positioning, installation, and assistance in the air. Aerial work is also highly dangerous, slow, and costly.

[0007] Equipment hoisting issues:

[0008] The site has high space requirements. Since the columns have already been installed, the space in front of and behind the columns is small, and larger equipment cannot be fully accessed for construction work. The construction safety requirements are high. The equipment operation is a delicate operation, and there is a high probability of damaging the cement pile foundation. The site requirements are also high. The project site is generally not very flat and has serious subsidence, making it difficult for equipment to enter. Or, after rain, the ground is wet and pitted, making it impossible to enter, which will affect the delivery date. Utility Model Content

[0009] To solve the above-mentioned technical problems, this utility model provides a photovoltaic bracket hoisting mechanism.

[0010] This utility model is achieved using the following technical solution: a photovoltaic bracket hoisting mechanism, including a supporting angle iron, a hoisting column fixedly connected to the top of the supporting angle iron, a fixing clamp fixedly connected to the left end of the hoisting column, a cement column inserted into the inside of the fixing clamp, a backing fixedly connected to the left end of the supporting angle iron, a bearing bracket fixedly connected to the bottom of the hoisting column, a rope loop one rotatably connected to the surface of the bearing bracket, a hemp rope rotatably connected to the surface of the rope loop one, a rope loop two rotatably connected to the surface of the hemp rope, a fixing bracket rotatably connected to the surface of the rope loop two, a hemp rope knot fixedly connected to the surface of the hemp rope, a roller frame rotatably connected to the surface of the hemp rope, and a hook fixedly connected to the bottom of the roller frame.

[0011] Based on the above technical solution, the schematic diagram of the single column inclined support assembly shows that this support assembly is composed of a set of combined support components. It consists of an inclined beam, a front inclined support, a rear inclined support, an angle steel column, and a clamp. The clamp has two semi-circular shapes with two wings extending outwards, each made of bent flat iron. The two wings are symmetrical on the left and right. When connecting, bolts are used to fix them and limit the angle iron, etc. It is the core component in the middle of the support, used to support the crossbeam, connect the column, and adjust the angle.

[0012] As a further improvement to the above scheme, the cement column is located at the left end of the hoisting column, the left end of the backing is in contact with the right end surface of the cement column, and the supporting angle iron is located at the right end of the cement column.

[0013] Using the above technical solutions, cement columns can be designed with circular cement pile foundations based on the actual site survey, and driven into the ground up to the load-bearing layer.

[0014] As a further improvement to the above solution, the fixed bracket is fixedly connected to the top of the hoisting column, and the roller frame is located at the bottom of the hoisting column.

[0015] By using the above technical solution, when a heavy object is lifted, the lifting column is prevented from bending towards the side of the heavy object. The support welded to the lifting column is used to resist the concrete column, which can reduce the deformation to a certain extent.

[0016] As a further improvement to the above solution, the hemp rope is located at the bottom of the hoisting column, the second rope loop is located at the bottom of the hoisting column, and the first rope loop is located at the bottom of the hoisting column.

[0017] With the above technical solution, as shown in the schematic diagram of the hoisting mechanism and the hoisting bracket, after the hook lifts the entire bracket, the rope on the right side is pulled downwards. Since it is pulled entirely by manpower, there are knots on a section of the rope on the right side, which can effectively increase the friction between the hand and the rope and reduce the effort required by the operator.

[0018] As a further improvement to the above scheme, the number of hemp rope knots is set to several, and the several hemp rope knots are distributed at equal intervals around the hemp rope.

[0019] As a further improvement to the above solution, the support is located at the top of the fixed clamp, and the number of fixed clamps is set to two, with the two fixed clamps symmetrically distributed front and back around the cement column.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model features a simple overall design for the hoisting mechanism, labor-saving hoisting rollers, and an anti-sinking design. It is a portable device that can be operated by a single person, greatly reducing labor costs. The hoisting mechanism is easy to operate, safe and reliable, has low training costs, and is easy to popularize on-site. The mechanism has simple parts, requires little operating space, and will not damage already installed columns, supports, etc. It has strong ground adaptability and can be operated in steep places such as mountains.

[0022] This utility model greatly improves work efficiency, reduces labor costs, and ensures workplace safety by setting up the overall equipment. The equipment hoisting can reduce the workload of workers, avoid accidental injuries and equipment damage, and reduce potential dangers in industrial production, thereby saving enterprises labor and insurance costs.
