Description

Technical Field

[0001] The invention relates to the technical field of elevator guide rail drilling, and in particular to a positioning drilling device for an elevator guide rail assembly. Background Art

[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates. They are the tracks in the elevator system that ensure the vertical movement of the car in the hoistway. They are divided into car guide rails and counterweight guide rails. They are divided into three types based on the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails also bear the impact force of the car and elevator during braking, as well as the impact force of the safety clamp during emergency braking. The elevator guide rails must be firmly fixed to the wall of the elevator hoistway and maintain strict straightness and verticality.

[0003] In order to install and fix the elevator guide rails, the elevator guide rails need to be drilled, and then bolts or other fasteners are used in conjunction with the formed holes to stably fix the elevator guide rails on the hoistway wall. The formed holes on the elevator guide rails can also be used as reference points for the guide rail installation position to ensure that the guide rails are accurately installed according to the design requirements. Therefore, drilling holes in the elevator guide rails is an indispensable step.

[0004] When drilling holes in T-shaped elevator guide rails, the existing technology usually first determines the specific location where the holes need to be drilled according to the requirements of the elevator installation drawings, then uses a measuring tool to mark the location where the holes need to be drilled on the guide rails, and then selects a suitable drill bit and drilling equipment to ensure that the diameter of the drill bit matches the expected fastener. The drilling equipment is then started and the drilling equipment performs drilling processing on the elevator guide rails. However, the drilling equipment used implements a single-station processing method, and each time a hole is drilled, a formed hole is formed, which reduces the efficiency. After completing the drilling of one side of the horizontal section of the elevator guide rail, the automatic side change function of the drill bit cannot be realized, and the elevator guide rail needs to be disassembled and fixed and installed again, which further reduces the drilling efficiency and increases the labor input.

The support unit 2 includes a first T-shaped plate 21 that is arranged below the L-shaped plate 14 and is inverted. First support columns 25 are installed at the four corners of the lower end of the horizontal section of the first T-shaped plate 21.

[0036] During the specific operation, initially, the first T-shaped plate 21 is placed on the ground below the L-shaped plate 14 through four first support columns 25 and fixed.

[0037] See also Figure 1 The elevator guide rail assembly positioning drilling device also includes an extension unit 3, which is connected to the left end of the first T-shaped plate 21 and is used to place the elevator guide rail.

[0038] See also Figure 1 , Figure 2 and Figure 8 The extension unit 3 includes a sliding countersunk hole 31 opened at the left end of the horizontal section of the first T-shaped plate 21, a sliding rod 35 is slidably connected in the sliding countersunk hole 31, an inverted second T-shaped plate 32 is installed at the left end of the sliding rod 35, two second support columns 34 are symmetrically installed at the lower end of the horizontal section of the second T-shaped plate 32, a second convex arc surface is provided at the upper end of the vertical section of the second T-shaped plate 32, and a plurality of evenly distributed second round balls 33 are rotatably connected to the upper end of the vertical section of the second T-shaped plate 32.

[0039] In specific operation, the second T-shaped plate 32 is initially pulled, and the second T-shaped plate 32 slides in the sliding counterbore 31 through the sliding rod 35, thereby changing the distance between the second T-shaped plate 32 and the first T-shaped plate 21. The second T-shaped plate 32 is placed on the ground through two second support columns 34, and then the elevator guide rail to be drilled is placed on the second T-shaped plate 32 (see Fig. 9 ), the second T-shaped plate 32 supports the elevator guide rail, and the vertical section of the second T-shaped plate 32 is inserted into the vertical section of the elevator guide rail, thereby guiding the movement of the elevator guide rail to avoid deviation of the elevator guide rail during movement.

[0043] During specific operation, the moving elevator guide rail moves toward the first T-shaped plate 21 and moves onto the first T-shaped plate 21. The vertical section of the first T-shaped plate 21 is located in the vertical section of the elevator guide rail, which guides the movement of the elevator guide rail. The first round ball 211 reduces the friction between the first T-shaped plate 21 and the elevator guide rail. After the two horizontal sections of the elevator guide rail move between the horizontal section of the first T-shaped plate 21 and the clamping component 23, the elevator guide rail continues to be moved so that its end is in close contact with the rectangular baffle 242, thereby achieving preliminary positioning of the drilling position of the elevator guide rail, and then stopping the movement of the elevator guide rail.

[0045] See also Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8The clamping component 23 includes a plurality of connecting plates 231 evenly distributed from left to right below the first T-shaped plate 21, two lifting columns 232 are symmetrically installed on the upper end of the connecting plate 231, and the lifting columns 232 slide through the horizontal section of the first T-shaped plate 21, and a return spring 233 is sleeved on the lower end of the lifting column 232, and the lower end of the return spring 233 is fixedly connected to the connecting plate 231, and the upper end of the return spring 233 is fixedly connected to the horizontal section of the first T-shaped plate 21, and the front and rear sides of the vertical section of the first T-shaped plate 21 are symmetrically provided with clamping plates 234, and the lower end of the clamping plate 234 is fixedly connected to the corresponding upper ends of the plurality of lifting columns 232, and a positioning hole 235 is opened on the left and right sides of the end close to the clamping plate 234, and a rectangular groove 236 is opened at the lower end of the clamping plate 234.

[0046] During specific operation, after the horizontal section of the elevator guide rail moves to below the clamping plate 234, the first hydraulic push rod 13 is started, and the first hydraulic push rod 13 drives the L-shaped plate 14 to descend, and the L-shaped plate 14 drives the alignment plate 16 to move downward and press down the corresponding clamping plate 234, and at the same time, the alignment plate 16 drives the two alignment protrusions 17 to insert into the corresponding positioning holes 235, so as to limit the downward movement position of the L-shaped plate 14, and the clamping plate 234 is forced to move downward and press down the corresponding multiple lifting columns 232, and the multiple lifting columns 232 are forced to drive the multiple connecting plates 231 to move downward, and the multiple connecting plates 231 drives the multiple lifting columns 232 on the other side to descend and stretch the multiple return springs 233. The multiple lifting columns 232 on the other side drive another clamping plate 234 to move downward, thereby realizing the function of the two clamping plates 234 to clamp and limit the horizontal section of the elevator guide rail. The two clamping plates 234 cooperate with the horizontal section of the first T-shaped plate 21 to realize the function of clamping and limiting the area around the drilling position of the elevator guide rail to avoid deformation of the elevator guide rail during the drilling process. The rectangular groove 236 on the clamping plate 234 is used to place the raised part of the horizontal section of the elevator guide rail and limit and lock it.

[0049] See also Figure 1-Figure 9During specific operation, the two transmission motors 154 are initially connected to the existing power supply, and the second hydraulic push rod 151 is connected to the external hydraulic pump. Before operation, according to the required hole diameter, the drill bit 155 of the required specification is passed through the corresponding guide through hole 1564 and installed in the clamping module 153. The clamping module 153 is an existing detachable installation mechanism. During the descending process of the L-shaped plate 14, the horizontal section of the L-shaped plate 14 drives the lower pressing plate 1561 to descend through the push rod seat. The lower end of the lower pressing plate 1561 is flush with the lower end of the alignment plate 16. The alignment plate 16 presses the clamping plate 234 while the lower pressing plate 1561 presses and limits the other pressing plate 234, and at the same time, the lower pressing plate 1561 drives the U-shaped pressing plate 1563 to move to the upper end of the elevator guide rail through the rectangular plate 1562 and presses it from the outside, further improving the stability of the elevator guide rail during drilling. The horizontal section of the L-shaped plate 14 also drives the second hydraulic push rod 151 to move downward through the push rod seat, and the second hydraulic push rod 151 drives the clamping module 153 and the drill bit 155 to move downward through the lifting plate 152.

[0050] See also Figure 1 and Figure 2 The drilling unit 1 further includes two positioning components 18 which are symmetrically distributed front and back and connected to the bottom wall of the positioning frame 11 , and a lifting component 19 is connected to the upper end of the horizontal section of the L-shaped plate 14 .

[0051] See also Figure 1 , Figure 5 , Figure 2 and Figure 7The lifting component 19 includes cylindrical rods 191 symmetrically installed on the left and right sides of the upper end surface of the L-shaped plate 14. There are two cylindrical rods 191. A lifting ring 192 is installed on the upper ends of the two cylindrical rods 191. Two lifting grooves 193 are symmetrically opened on the upper ends of the lifting rings 192.

[0052] During specific operation, after drilling on one side of the horizontal section of the elevator guide rail is completed, the second hydraulic push rod 151 drives the lifting plate 152 to reset upward, and the lifting plate 152 drives the two drill bits 155 to reset through two clamping modules 153, and then the first hydraulic push rod 13 is started, and the first hydraulic push rod 13 drives the L-shaped plate 14 to rise and reset, and the L-shaped plate 14 drives the drilling component 15 to rise and drives the lifting ring 192 to move upward through two cylindrical rods 191.

[0053] See also Figure 1 , Figure 5 and Figure 6 The driving component 12 includes a rotating disk 121 rotatably connected to the bottom wall of the positioning frame 11, and the upper end of the rotating disk 121 is fixedly connected to the output shaft of the driving motor 122. The driving motor 122 is fixedly connected to the bottom wall of the positioning frame 11, and two locking rods 123 located below the positioning frame 11 are symmetrically installed on the annular surface of the rotating disk 121.

[0055] During the specific operation, the driving motor 122 is initially connected to an external power source, and the U-shaped frame 181 limits the positioning rod 123 at the corresponding position, thereby realizing the function of limiting the rotating disk 121 and ensuring the stability of the drilling process. The rising lifting ring 192 pushes the two U-shaped frames 181 upward, and the two vertical sections of the U-shaped frame 181 gradually separate from the positioning rod 123 and stretch the connecting spring 182. At the same time, the two lifting grooves 193 on the lifting ring 192 and the two positioning rods 123 are The two U-shaped frames 181 release the limit of the two positioning rods 123. At this time, the lower ends of the two positioning protrusions 17 exceed the upper ends of the elevator guide rails. Then, the driving motor 122 is started, and the driving motor 122 drives the rotating disk 121 to rotate. The rotating disk 121 drives the first hydraulic push rod 13 to rotate. The first hydraulic push rod 13 drives the L-shaped plate 14 to rotate. The L-shaped plate 14 drives the drilling component 15 to rotate. The rotating disk 121 rotates 180° to achieve the desired effect. The function of changing sides of the drilling component 15 is now reduced, which reduces the operation of repeatedly installing the limit position of the elevator guide rail and reduces the labor input. Subsequently, the drive motor 122 is turned off, and the first hydraulic push rod 13 drives the L-shaped plate 14 to move downward.
