A temporary lighting bracket for construction sites

Abstract

This utility model provides a temporary lighting bracket for construction sites, relating to the field of building construction auxiliary technology. It includes: a supporting base plate, with a conical soil-breaking component fixedly installed at the axial center of the bottom end face of the supporting base plate, and spiral blades fixedly installed on the conical surface of the conical soil-breaking component. With the conical soil-breaking component and spiral blades, the operator only needs to hold the ring grip a, apply pressure, and rotate to drill the bracket into the ground. No additional tools such as hammers or drills are required; a single person can complete the fixing, significantly shortening the installation time. The structure of the conical soil-breaking component, which penetrates deep into the soil, can resist external forces such as collisions with personnel common on construction sites, reducing the risk of the bracket tipping over. This solves the problems of existing temporary lighting brackets with base counterweight rod fixing and deep piling installation methods, which suffer from laborious handling and placement, easy tipping on uneven ground such as muddy slopes, complex operation relying on specialized equipment, requiring multiple people to cooperate, and low installation efficiency.

Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for building construction, and in particular to a temporary lighting bracket for construction sites. Background Technology

[0002] At construction sites for buildings, municipal works, roads, and bridges, temporary lighting is a core infrastructure ensuring safety and accuracy during nighttime or low-light conditions. However, existing temporary lighting brackets for construction sites mostly employ two installation methods: base counterweight and pole fixing, or deep burial with piles. The former requires stacking heavy objects such as sandbags and cement blocks on the base to prevent tipping, which is not only time-consuming and labor-intensive to move and place, but also prone to tipping over on uneven ground such as muddy slopes. The latter requires the use of impact drills, hammers, and other tools to drive metal piles into the ground, which is complex and relies on specialized equipment. In addition, both installation methods require multiple people to work together, resulting in low installation efficiency and failing to meet the needs of rapid deployment and immediate lighting at construction sites. Utility Model Content

[0003] This utility model relates to a temporary lighting bracket for construction sites, which solves the problems of existing temporary lighting brackets with two installation methods: base counterweight rod fixing and deep piling. These methods are laborious to carry and place, prone to tipping over on uneven ground such as muddy slopes, complicated to operate and dependent on professional equipment, require multiple people to cooperate and have low installation efficiency, and are difficult to meet the needs of rapid on-site deployment and immediate lighting.

[0004] This utility model provides a temporary lighting bracket for construction sites, specifically including: a supporting base plate, a conical soil-breaking component fixedly installed at the axial center of the bottom end face of the supporting base plate, and a spiral blade fixedly installed on the conical surface of the conical soil-breaking component; a rotating auxiliary column provided above the supporting base plate, a locking block fixedly installed at the bottom end face of the rotating auxiliary column, and a rotating shaft fixedly installed at the axial center of the bottom end face of the locking block, the rotating shaft being rotatably connected to the axial center of the top end face of the supporting base plate via a bearing; a flange a fixedly installed on the top of the outer circumference of the rotating auxiliary column; an additional column, the number of which can be increased or decreased, provided above the rotating auxiliary column, with flange b fixedly installed at the top and bottom of the outer circumference of the additional column, flange b being connected to the flange a at the bottom of the additional column; a mounting base provided above the additional column, an extension column fixedly installed at the center of the bottom end face of the mounting base, and a flange c fixedly installed at the bottom of the outer circumference of the extension column, flange c being connected to the flange a at the top of the additional column.

[0005] Furthermore, a wiring groove is provided at the axial center of the bottom end face of the extension column; the mounting base has a hexagonal frustum structure, and a wiring hole connected to the wiring groove is provided on each of the six side end faces of the mounting base.

[0006] Furthermore, a wiring mating hole is provided at the axial center of the expansion column, penetrating both the top and bottom surfaces of the expansion column; when flange c is installed and connected to flange a at the top of the expansion column, the wiring mating hole corresponds to the wiring mating groove; a wiring channel is provided between the top surface and the outer circumferential surface of the rotating auxiliary column; when flange b is installed and connected to flange a at the bottom of the expansion column, the wiring mating hole corresponds to the top opening of the wiring channel.

[0007] Furthermore, an annular grip ring a is provided on the top of the supporting base plate, and the annular grip ring a is fixedly connected to the top surface of the supporting base plate by a connecting rod a.

[0008] Furthermore, the outer periphery of the rotating auxiliary column is provided with an annular grip ring b, which is coaxially arranged with the rotating auxiliary column. The annular grip ring b is fixedly connected to the outer circumferential surface of the rotating auxiliary column by a connecting rod b. The top surface of the locking block has three threaded through holes in an annular array, which penetrate the bottom surface of the locking block. Each of the three threaded through holes is threaded with a set of locking bolts.

[0009] This utility model provides a temporary lighting bracket for construction sites, which has the following beneficial effects: This utility model features a bottom conical soil-breaking component paired with spiral blades, mimicking the principle of an auger drill. Operators only need to hold the ring grip a, apply pressure, and rotate it to drill the support into the ground. No additional tools such as hammers or drills are required, and a single person can complete the fixing, significantly shortening the installation time. Furthermore, the support base plate forms a stable base after it is in contact with the ground. Combined with the structure of the conical soil-breaking component that penetrates deep into the soil, it can resist external forces such as personnel collisions commonly seen on construction sites, reducing the risk of the support tipping over. It eliminates the need for repeated inspections and reinforcements, reducing the workload of later maintenance.

[0010] This utility model can quickly adjust the overall height of the bracket by increasing or decreasing the number of additional columns to meet the needs of low-altitude lighting or high-altitude large-area lighting. The mounting base adopts a hexagonal frustum structure with pre-drilled wiring holes on all six side faces, which can simultaneously fix six lighting devices to meet all-round lighting needs. This utility model constructs a wiring channel. The power cord of the lighting device enters from the wiring hole of the mounting base, passes through the wiring matching groove of the extension column and the wiring matching hole of the additional column, and finally exits from the wiring channel of the rotating auxiliary column. The entire process is hidden inside the bracket, which complies with the temporary power safety regulations for construction sites.

[0011] This utility model's rotating auxiliary column is rotatably connected to the supporting base plate via a rotating shaft and bearings, enabling the entire upper structure to rotate 360°. When the temporary power supply position is adjusted at the construction site, there is no need to disassemble and reinstall the bracket; simply hold the ring grip b and push to rotate, which will align the cable routing channel with the power supply direction, avoiding damage caused by cable pulling. It is suitable for the needs of frequent changes in power supply position in construction scenarios. After the angle adjustment is completed, the position of the rotating auxiliary column can be quickly fixed by tightening the three sets of locking bolts on the locking block, forming a three-point uniform force limiting structure to prevent the bracket from rotating on its own under the action of external forces such as wind and vibration.

A flange c403 is fixedly installed on the bottom of the outer periphery of the extension column 402. The flange c403 is connected to the flange a204 at the top of the supplementary column 3. A wiring groove 404 is provided at the axial part of the bottom end face of the extension column 402. The mounting base 4 has a hexagonal frustum structure. A wiring hole 401 connected to the wiring groove 404 is provided on each of the six side end faces of the mounting base 4. A through hole is provided at the axial part of the supplementary column 3, penetrating the top and bottom surfaces of the supplementary column 3. The wiring mating hole 302 on the surface; when the flange c403 is installed and connected to the flange a204 at the top of the auxiliary column 3, the wiring mating hole 302 corresponds to the wiring mating groove 404; a wiring channel 203 is opened between the top surface and the outer peripheral surface of the rotating auxiliary column 2; when the flange b301 is installed and connected to the flange a204 at the bottom of the auxiliary column 3, the wiring mating hole 302 corresponds to the top opening end of the wiring channel 203.

[0017] Among them, the supporting base plate 1 is provided with an annular grip ring a103 arranged coaxially with it, and the annular grip ring a103 is fixedly connected to the top surface of the supporting base plate 1 by a connecting rod a104; the rotating auxiliary column 2 is provided with an annular grip ring b205 arranged coaxially with it, and the annular grip ring b205 is fixedly connected to the outer circumferential surface of the rotating auxiliary column 2 by a connecting rod b206; the top surface of the locking block 201 has three threaded through holes 207 in an annular array, which penetrate the bottom surface of the locking block 201, and a set of locking bolts 202 are threadedly installed in each of the three threaded through holes 207.

[0018] The working principle of this embodiment: The conical soil-breaking component 101 of this lighting bracket has a sharp conical structure. The spiral blade 102 fixed on its conical surface imitates the principle of a "spiral drill". When in use, the operator holds the annular grip a103 above the support base plate 1, applies downward pressure and rotates. The spiral blade 102 will gradually cut the soil and discharge it upward, so that the conical soil-breaking component 101 can quickly drill into the ground until the support base plate 1 is in contact with the ground, completing the initial fixation of the bottom of the lighting bracket. Stable implantation can be achieved without additional tools. According to lighting needs (such as low-altitude local lighting and high-altitude large-area lighting), the number of additional columns 3 can be increased or decreased: a single additional column 3 can be fixed to the flange a204 at the top of the rotating auxiliary column 2 by bolts through the bottom flange b301; multiple additional columns 3 can be spliced ​​together by the upper and lower flanges b301 in sequence, and finally connected to the flange b301 of the topmost additional column 3 through the flange c403 of the bottom extension column 402 of the mounting base 4, so as to realize the flexible adjustment of the bracket height and meet the different lighting height requirements; Mounting base 4 adopts a hexagonal frustum structure, with wiring holes 401 on all six side faces, allowing for the simultaneous installation of six lighting devices (such as LED floodlights and emergency lights). The devices are fixed to the side faces of mounting base 4 with bolts. The wiring holes 401 provide a passage for the lighting device connection cables. The specific wiring path is as follows: the power cable of the lighting device passes through the wiring hole 401 and enters the wiring groove 404 at the bottom of the extension column 402; when flange c403 is connected to the top flange b301 of the auxiliary column 3... The wiring groove 404 is precisely aligned with the wiring hole 302 on the axis of the auxiliary column 3, and the power cable can pass through the wiring hole 302 in sequence. Similarly, when the bottom flange b301 of the auxiliary column 3 is connected to the top flange a204 of the rotating auxiliary column 2, the wiring hole 302 is aligned with the top opening of the wiring channel 203 of the rotating auxiliary column 2, and the power cable is finally led out from the side opening of the wiring channel 203 and connected to the temporary power supply (such as the distribution box or generator) on the construction site to achieve safe power supply. Furthermore, since the rotating auxiliary column 2 and the supporting base plate 1 are rotatably connected through the rotating shaft 208 and the bearing 105, they can achieve 360° horizontal rotation. When the temporary power supply at the construction site is repositioned, the operator can hold the annular grip b205 around the rotating auxiliary column 2 and push the rotating auxiliary column 2 to rotate around the rotating shaft 208, causing the upper auxiliary column 3, the mounting base 4 and the lighting equipment to rotate synchronously, so that the wiring channel 203 can be adjusted in angle with the temporary power supply. After the adjustment is completed, the operator can use a tool to rotate the locking bolt 202, so that it moves downward along the threaded through hole 207 until the bottom end of the locking bolt 202 presses against the supporting base plate 1, forming a three-point support, thereby limiting and fixing the rotating auxiliary column 2 and preventing it from rotating.
