An engineering surveying and setting-out device

Abstract

This utility model belongs to the technical field of engineering measurement equipment, and particularly relates to an engineering measurement line laying device, including a base, a line laying roller, a drive motor, a clamping screw, and a rotary cleaning structure. In this utility model, after the measurement is completed, the line needs to be retrieved. During retrieval, the output shaft of the drive motor rotates, which in turn drives a synchronous pulley to rotate. Under the action of the synchronous belt, another synchronous pulley rotates, and at the same time, the synchronous pulley drives the active bevel gear to rotate. Under the meshing action, the active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the rotating drum and the cleaning brush to rotate. When the cleaning brush rotates, it sweeps the line, removing dust particles or impurities attached to the line. The inside of the line laying roller is hollow, and the surface of the roller has a circumferentially formed flow groove. The flow groove ensures air circulation, keeps the line dry, and prevents the line from being damaged by moisture and shortening its service life.

Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying equipment technology, and in particular relates to an engineering surveying and setting-out device. Background Technology

[0002] In the field of engineering construction, surveying and setting out is a preliminary process to ensure construction accuracy. Its main function is to transform the abstract coordinates, dimensions, and spatial relationships in the design drawings into physical markers that can be operated on the ground, providing a benchmark for subsequent foundation excavation and structural construction. Announcement No. CN218329954U discloses an engineering surveying and setting out device. This device releases the line by rotating a first motor. After use, the line can be retrieved by reversing the output shaft of the first motor. However, during use, dust, sand particles, and various impurities flying in the construction environment easily adhere to the line. When retrieving the line, these impurities are not cleaned before it is directly wound onto the output shaft of the first motor. Furthermore, because the output shaft is a solid structure, the contact area between the line near the output shaft and the outside air is reduced during winding and retrieval, resulting in poor air permeability. Since the construction environment is often damp, the line encased inside is in a closed, humid, and hot state for a long time, which easily breeds mold and produces irritating odors, leading to a shortened lifespan of the line. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] This invention provides an engineering measurement and laying-out device to address the problem that when wires are wound directly onto the output shaft of a first motor without cleaning impurities during recycling, and because the output shaft is a solid structure, the wires near the output shaft are prone to mold growth and produce an irritating odor.

[0005] (II) Technical Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An engineering surveying and setting-out device includes a base and a setting-out roller. Elevating bases are installed on both sides of the base. A drive motor is installed on one of the elevated bases, and a clamping screw is threadedly connected to the other elevated base. The setting-out roller is clamped between the drive motor and the clamping screw. A protective outer cylinder is installed between the two elevated bases, and a rotary cleaning structure is provided in the protective outer cylinder.

[0008] Furthermore, a docking block is inserted into the output shaft end of the drive motor. The docking block is polygonal in shape, and docking rods are fixed to both sides of the wire feeding roller. A first docking port is opened at the end of the docking rod near the docking block. The first docking port is adapted to the docking block and is inserted together with the docking block.

[0009] Furthermore, a ball bearing is slidably embedded at one end of the clamping screw, and a second docking port is provided at the end of the docking rod near the ball bearing. The second docking port is adapted to the ball bearing and is inserted into the ball bearing.

[0010] There is a gap between the clamping screw and the corresponding connecting rod, and the other end of the clamping screw is fixedly connected to a lever in a circular shape.

[0011] Furthermore, the inside of the wire feeding roller is hollow, and the surface of the roller body is provided with a flow groove in a circular shape. Side stops are provided on both sides of the wire feeding roller, and through holes connected to the flow groove are provided on the side stops.

[0012] Furthermore, the protective outer cylinder includes a lower protective outer cylinder and an upper protective outer cylinder. The two sides of the lower protective outer cylinder are fixed to two raised bases through brackets, and the upper protective outer cylinder is fixed to the lower protective outer cylinder through bolts and nuts.

[0013] Furthermore, an inner sleeve is provided on the lower protective outer cylinder. The rotary cleaning structure includes two rotating cylinders, which are on the same axis and are fixedly connected by a connecting rod. The rotating cylinders are provided with through holes. At least two sets of spiral rods are fixedly connected to the two rotating cylinders in a circumferential manner. A cleaning brush is sleeved on the spiral rod, and the bristles of the cleaning brush are located at the through holes.

[0014] Furthermore, the same funnel-shaped conductor tube is snapped onto the same end of the lower and upper protective outer cylinders, and the outlet end of the conductor tube is on the same axis and connected to the two through holes.

[0015] Furthermore, both rotating cylinders are rotatably inserted into the inner sleeve, and a portion of one of the rotating cylinders extends out of the inner sleeve, with the extended inner sleeve fixedly fitted with a driven bevel gear.

[0016] A semi-circular lower support sleeve is provided on one side of the lower protective outer cylinder, and an inverted semi-circular upper support sleeve is provided on one side of the upper protective outer cylinder. The lower support sleeve and the upper support sleeve are rotatably connected by the same drive shaft. One end of the drive shaft extends into the interior of the lower protective outer cylinder and the end is fixedly connected to a drive bevel gear that meshes with the driven bevel gear.

[0017] Synchronous pulleys are fixedly fitted on both the drive shaft and the output shaft of the drive motor, and the two synchronous pulleys are connected by a synchronous belt.

[0018] Furthermore, the inner sleeve is provided with a drain port, which passes through the lower protective outer sleeve and connects to the outside.

[0019] A collection tube is inserted into the base, and the collection tube is located directly below the outlet.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. In this utility model, after the measurement is completed, the wire needs to be retrieved. Simply drive the drive motor to rotate the docking block in the opposite direction through its rotating shaft. Under the action of the docking block and the docking rod, the wire feeding roller rotates in the opposite direction, thereby retrieving the wire at a certain speed. During the wire feeding or retrieving process, the output shaft of the drive motor will also drive the synchronous pulley to rotate when it rotates. Under the action of the synchronous belt, it will drive another synchronous pulley to rotate. At the same time, the synchronous pulley will drive the active bevel gear to rotate. Under the meshing action, it will drive the driven bevel gear to rotate. The driven bevel gear will drive the rotating drum and the cleaning brush to rotate. When the cleaning brush rotates, it will sweep the wire and remove the dust particles or impurities attached to the wire.

[0023] Second, in this utility model, the inside of the roller body of the feeding roller is hollow and the surface of the roller body is provided with a circumferential flow groove. The flow groove can ensure the air circulation, keep the thread dry, and prevent the thread from being damaged due to moisture and shortening its service life.

[0024] The through holes allow air to flow from both sides of the feed roller into its interior, and then out through the flow channels, ensuring ventilation and dryness inside the wire.

[0025] Third, in this utility model, after the rolling ball engages with the second docking port, a gap is left between the clamping screw and the corresponding docking rod to prevent the docking rod from rubbing against the clamping screw when the pay-off roller rotates to pay off the wire. The rolling ball limits the pay-off roller while not affecting its rotation. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] like Figures 1-10 As shown, an engineering surveying and setting-out device includes a base 1 and a setting-out roller 2. Elevating bases 11 are installed on both sides of the base 1. One of the elevated bases 11 is equipped with a drive motor 3, and the other elevated base 11 is threadedly connected to a clamping screw 4. The setting-out roller 2 is engaged between the drive motor 3 and the clamping screw 4. Specifically, a docking block 31 is inserted into the output shaft end of the drive motor 3. The docking block 31 is polygonal in shape. A docking rod 21 is fixed to both sides of the setting-out roller 2. A first docking port 2101 is opened at the end of the docking rod 21 near the docking block 31. The first docking port 2101 is adapted to the docking block 31, and the first docking port 2101 is inserted into the docking block 31.

[0040] Furthermore, a ball bearing 41 is slidably embedded at one end of the clamping screw 4, and a second docking port 2102 is provided at the end of the docking rod 21 near the ball bearing 41. The second docking port 2102 is adapted to the ball bearing 41 and is inserted into the ball bearing 41.

[0041] The other end of the clamping screw 4 is fixedly connected to a lever 42 in a circular shape.

[0042] Specifically, during installation, the measuring wire is first wound onto the feed roller 2. Then, one side of the feed roller 2 is inserted into the first docking socket 2101 via the docking rod 21. Then, the lever 42 is rotated, which drives the clamping screw 4 to rotate. Under the action of thread engagement, the end of the clamping screw 4 with the rolling ball 41 moves along the side close to the feed roller 2 until the rolling ball 41 is engaged in the second docking socket 2102. After the rolling ball 41 is engaged with the second docking socket 2102, there is a gap between the clamping screw 4 and the corresponding docking rod 21 to avoid friction between the docking rod 21 and the clamping screw 4 when the feed roller 2 rotates to feed the wire. The rolling ball 41 limits the feed roller 2 while not affecting its rotation.

[0043] Furthermore, the measuring wire is tied to the feed roller 2. The feed roller 2 has a hollow interior and a circumferentially shaped flow groove 201 on its surface. The flow groove 201 ensures air circulation, keeping the wire dry and preventing damage from moisture, thus extending its service life. Side guards 22 are provided on both sides of the feed roller 2. These side guards limit the wire and prevent it from falling off the sides of the feed roller 2 during the feeding process. The side guards 22 have through holes 2201 that communicate with the flow groove 201. Through the through holes 2201, air flows from the sides of the feed roller 2 into its interior and then out through the flow groove 201, ensuring ventilation and dryness inside the wire.

[0044] A protective outer cylinder is installed between the two raised bases 11. The protective outer cylinder is equipped with a rotating cleaning structure. Specifically, the protective outer cylinder includes a lower protective outer cylinder 5 and an upper protective outer cylinder 51. The two sides of the lower protective outer cylinder 5 are fixed to the two raised bases 11 through brackets. The upper protective outer cylinder 51 is fixed to the lower protective outer cylinder 5 through bolts and nuts.

[0045] Furthermore, an inner sleeve 52 is provided on the lower protective outer cylinder 5. The rotary cleaning structure includes two rotating cylinders 6, which are located on the same axis and are fixedly connected by a connecting rod. A through hole 601 is provided on the rotating cylinder 6. At least two sets of spiral rods 61 are fixedly connected in a circumferential manner between the two rotating cylinders 6. A cleaning brush 62 is sleeved on the spiral rod 61, and the bristles of the cleaning brush 62 are located at the through hole 601.

[0046] Furthermore, the same funnel-shaped wire tube 8 is snapped onto the same end of the lower protective outer cylinder 5 and the upper protective outer cylinder 51. The outlet end of the wire tube 8 is on the same axis and connected to the two through holes 601. The funnel-shaped wire tube 8...

[0047] Specifically, when threading the wire, the bolts and nuts used to fix the upper protective outer cylinder 51 and the lower protective outer cylinder 5 are removed, thereby disassembling the upper protective outer cylinder 51. Then, the output shaft of the drive motor 3 drives the docking block 31 to rotate. Under the docking action of the docking block 31 and the docking rod 21, the wire feeding roller 2 is rotated, thereby releasing a part of the wire. Then, the free end of the wire is passed through the wire tube 8 and the two through holes 601 in sequence. Finally, the upper protective outer cylinder 51 is fixed to the lower protective outer cylinder 5 again with bolts and nuts.

[0048] Furthermore, both rotating cylinders 6 are rotatably inserted into the inner sleeve 52, and a portion of one of the rotating cylinders 6 extends out of the inner sleeve 52, and the extended inner sleeve 52 is fixedly fitted with a driven bevel gear 63.

[0049] A semi-circular lower support sleeve 501 is provided on one side of the lower protective outer cylinder 5, and an inverted semi-circular upper support sleeve 5101 is provided on one side of the upper protective outer cylinder 51. The lower support sleeve 501 and the upper support sleeve 5101 are rotatably connected to the same drive shaft 64. The lower support sleeve 501 can support and protect the lower half of the drive shaft 64, and the upper support sleeve 5101 can support and protect the upper half of the drive shaft 64. One end of the drive shaft 64 extends into the lower protective outer cylinder 5 and is fixedly connected to a driving bevel gear 65 that meshes with the driven bevel gear 63.

[0050] Both the drive shaft 64 and the output shaft of the drive motor 3 are fixedly fitted with synchronous pulleys 32, and the two synchronous pulleys 32 are connected by a synchronous belt 33.

[0051] Specifically, during the wire feeding process, the worker pulls the end of the wire and drives the docking block 31 to rotate through the output shaft of the drive motor 3. Under the docking action of the docking block 31 and the docking rod 21, the wire feeding roller 2 rotates, thereby releasing the wire at a certain speed.

[0052] After the measurement is completed, the wire needs to be recycled. Simply drive the drive motor 3 to rotate the docking block 31 in the opposite direction through its rotating shaft. Under the docking action of the docking block 31 and the docking rod 21, the wire feeding roller 2 rotates in the opposite direction, thereby recycling the wire at a certain speed.

[0053] During the unwinding or rewinding of the wire, the output shaft of the drive motor 3 rotates, which in turn drives the synchronous pulley 32 to rotate. Under the action of the synchronous belt 33, the synchronous pulley 32 drives another synchronous pulley 32 to rotate. At the same time, the synchronous pulley 32 drives the driving bevel gear 65 to rotate, which in turn drives the driven bevel gear 63 to rotate. The driven bevel gear 63 drives the rotating drum 6 and the cleaning brush 62 to rotate. When the cleaning brush 62 rotates, it sweeps the wire to remove dust particles or impurities attached to the wire.

[0054] Furthermore, the inner sleeve 52 is provided with a drain port 5201, which penetrates the lower protective outer sleeve 5 and connects to the outside.

[0055] A collection tube 7 is inserted into the base 1, and the collection tube 7 is located directly below the outlet 5201.

[0056] Specifically, after the cleaning brush 62 removes the dust particles or impurities attached to the line body, the dust particles or impurities will fall into the collection cylinder 7 along the discharge port 5201 for collection.

[0057] In summary, the workflow of this utility model is as follows:

[0058] When installing the pay-off roller 2: First, wind the measuring wire onto the pay-off roller 2. Then, insert one side of the pay-off roller 2 into the first docking socket 2101 through the docking rod 21. Then, rotate the lever 42, which will drive the clamping screw 4 to rotate. Under the action of thread engagement, the end of the clamping screw 4 with the rolling ball 41 will move along the side close to the pay-off roller 2 until the rolling ball 41 is engaged in the second docking socket 2102.

[0059] When threading the wire, remove the bolts and nuts used to fix the upper protective outer cylinder 51 and the lower protective outer cylinder 5, thereby removing the upper protective outer cylinder 51. Then, drive the docking block 31 to rotate through the output shaft of the drive motor 3. Under the docking action of the docking block 31 and the docking rod 21, drive the wire feeding roller 2 to rotate, thereby releasing part of the wire. Then, pass the free end of the wire through the wire tube 8 and the two through holes 601 in sequence. Finally, fix the upper protective outer cylinder 51 to the lower protective outer cylinder 5 again with bolts and nuts.

[0060] When in use, the staff pulls the end of the line and drives the docking block 31 to rotate through the output shaft of the drive motor 3. Under the docking action of the docking block 31 and the docking rod 21, the feed roller 2 rotates, thereby releasing the line at a certain speed.

[0061] After the measurement is completed, the wire needs to be recycled. Simply drive the drive motor 3 to rotate the docking block 31 in the opposite direction through its rotating shaft. Under the docking action of the docking block 31 and the docking rod 21, the wire feeding roller 2 rotates in the opposite direction, thereby recycling the wire at a certain speed.

[0062] During the unwinding or rewinding of the wire, the output shaft of the drive motor 3 rotates, which in turn drives the synchronous pulley 32 to rotate. Under the action of the synchronous belt 33, the synchronous pulley 32 rotates, which in turn drives the driving bevel gear 65 to rotate. Under meshing action, the driving bevel gear 63 rotates, which in turn drives the driven bevel gear 63 to rotate. The driven bevel gear 63 drives the rotating drum 6 and the cleaning brush 62 to rotate. When the cleaning brush 62 rotates, it sweeps the wire, removing dust particles or impurities attached to the wire. After the cleaning brush 62 removes the dust particles or impurities attached to the wire, the dust particles or impurities fall into the collection drum 7 through the discharge port 5201 for collection.

[0063] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 3 are commonplace and are all conventional methods or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
