Description

Technical Field

[0001] The present application relates to the technical field of installation platforms, and in particular to a split and combined installation platform. Background Art

[0002] In recent years, with the continuous increase in the types and quantity of processing products of charge core mold tooling, the height and diameter of the core mold have increased, and the joint training of the charge core mold requires a vertical installation at 90° vertical to the ground. Specifically, the main core rod is first lifted and vertically installed into the chuck on the ground. After the bottom end of the main core rod is firmly fixed, the installation platform is used to allow the staff to stand on the installation platform to install the bottom wing and top wing of the main core rod in turn. Under this joint training process requirement, the main core rod needs to be lifted vertically by a crane so that the bottom end of the main core rod passes through the top of the installation platform. In this way, the lifting height of the crane needs to be at least 2.5 times the height of the main core rod.

[0003] However, the lifting height of the overhead crane used in the workshop is about 7 meters, and it is difficult to install the main core rod over 3 meters in the workshop. If the charge core mold is installed outside the workshop, a truck crane is required, and the weather conditions must be considered to avoid product contamination and ensure the safety of the co-training personnel. Therefore, in order to solve the above technical problems, there is an urgent need for an installation platform that can fix the core rod in parts and then reassemble it, and use it to install the bottom fin and top fin of the main core rod.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0036] refer to Figures 1 to 9 , split combined installation platform, including:

[0037] The chuck 100 is arranged on the reference surface and is used to clamp the bottom end of the mandrel 200; the chuck 100 may be a three-jaw chuck, and its specific model and specification may be selected and purchased according to actual needs, and this application does not specifically limit it. The specific clamping of the bottom end of the mandrel 200 by the chuck 100 may refer to the working principle of the three-jaw chuck in the prior art. The reference surface may be the floor of a workshop where the charge core mold is trained.

[0038] There are two first mounting platforms 300, and the top surfaces of the two first mounting platforms 300 are both provided with semicircular through holes 301. The two first mounting platforms 300 are fixed together by the first fasteners 400 and the two through holes 301 are combined to form a circular fixed through hole 3011 for accommodating the core rod 200. In actual use, after the bottom end of the core rod 200 is clamped and fixed by the chuck 100, one first mounting platform 300 is pulled close to the core rod 200 and the through hole 301 thereon is close to the peripheral wall of the core rod 200, and then the other first mounting platform 300 is pulled close to the core rod 200 and the through hole 3011 thereon is close to the peripheral wall of the core rod 200, and finally the two first mounting platforms 300 are fixed together by the first fasteners 400, so that the fixed through hole 3011 formed by the two through holes 301 on the two first mounting platforms 300 fixes the core rod 200, thereby improving the stability of the fixation of the core rod 200. Among them, the first fastener 400 may include a second fastening bolt and a nut, and a third threaded through hole matching the second fastening bolt is opened on the two first mounting platforms 300, and the screw end of the second fastening bolt passes through the third threaded through hole on one of the first mounting platforms 300 and the third threaded through hole on the other first mounting platform 300 in sequence and a nut is screwed thereon, thereby achieving the fixation of the first two mounting platforms 300.

[0039] The first staircase 500 is arranged on one side of one of the first installation platforms 300, and is used for workers to climb to the top surfaces of the two first installation platforms 300 and install parts on the peripheral wall of the mandrel 200. The material and shape of the first staircase 500 can be set according to actual needs, and the purpose is to serve as a bridge for workers to reach the first installation platform 300, thereby improving the convenience of workers to reach the top surface of the first installation platform 300 from the reference surface.

[0040] The split combined installation platform provided in the present application clamps the bottom end of the core rod 200 through the chuck 100, and the semicircular through holes 301 on the two first installation platforms 300 are sleeved on the outer wall of the core rod 200, and the two first installation platforms 300 are fixed together through the first fastener 400, thereby realizing the fixation of the two first installation platforms 300 to the core rod 200. The staff climbs to the top surface of the first installation platform 300 through the first staircase 500 to install the parts required on the top of the core rod 200. The above process does not require the lifting of the core rod 200 and the installation of the parts on the top of the core rod 200 can be realized in the production workshop. Moreover, the two first installation platforms 300 can not only facilitate the installation of the parts on the top of the core rod 200, but also fix the core rod 200, thereby realizing the stability of the parts installation process on the core rod 200 and improving the safety of the staff's operation process.

[0041] In some embodiments, reference Figure 1 and Figure 2 , each first mounting platform 300 in the present application includes a first concave plate 302, a second concave plate 303 and a mounting plate 304; specifically, the size of the second concave plate 303 is smaller than the size of the first concave plate 302 and its thickness is smaller than the thickness of the mounting plate 304, the first concave plate 302 is located directly below the second concave plate 303 and the two are connected by a support frame 600, the mounting plate 304 is installed at the notch of the second concave plate 303, and the through hole 301 is opened on the mounting plate 304. Among them, since the through hole 301 is opened on the mounting plate 304, and the fixed through hole 3011 formed by the two through holes 301 is used to fix the mandrel 200, therefore, the larger the thickness of the mounting plate 304, the deeper the fixed through hole 3011 can be, and the larger the contact area and height between the inner peripheral wall of the fixed through hole 3011 and the outer peripheral wall of the mandrel 200 are, thereby improving the stability of the fixed through hole 3011 fixing the mandrel 200. In addition, the mounting plate 304 can be installed at the notch of the second concave plate 303 by welding, and the bottom and top ends of the support frame 600 are respectively connected to the upper surface of the first concave plate 302 and the lower surface of the second concave plate 303, and the support frame 600 can be made of stainless steel, and its height is set according to the height of the mandrel 200 to be fixed, and the sizes of the first concave plate 302, the second concave plate 303 and the mounting plate 304 can be set according to actual needs. Therefore, this application does not further limit it here.

[0042] In some embodiments, reference Figure 1 , Figure 2 and Figure 6 In the present application, the lower surface of each first concave plate 302 is provided with casters 3021. The first mounting platform 300 can be moved to the position where the mandrel 200 needs to be fixed by the casters 3021, making the movement process of the first mounting platform 300 more labor-saving, thereby improving the convenience of the movement of the first mounting platform 300.

[0043] In some embodiments, reference Figure 1 , Figure 3 and Figure 6A plurality of clamping blocks 3022 are evenly spaced on the circumferential side of the first concave plate 302 in the present application, a first threaded through hole 3023 is opened on the clamping block 3022, a threaded rod 700 is passed through the internal thread of the first threaded through hole 3023, a footrest 701 is rotatably provided at the bottom end of the threaded rod 700, and a hand wheel 702 is provided at the top end of the threaded rod 700. Among them, a slot matching the thickness of the first concave plate 302 is opened on the clamping block 302, and the first clamping block 3022 is clamped on the first concave plate 302 through the slot. After the first mounting platform 300 is moved to the position where the core rod 200 needs to be fixed by the caster 3021, the bottom end of the threaded rod 700 is driven to rotate on the foot support 701 by the handwheel 702, so that the clamping block 3022 moves vertically up and down on the threaded rod, thereby making the caster 3021 at the bottom of the first concave plate 302 detach from the reference surface, preventing the caster 3021 from sliding on the reference surface, thereby improving the stability of the first mounting platform 300 during the fixing process of the core rod 200. In addition, by rotating the threaded rod 700 through the hand wheel 702, the height of each clamping block 3022 on the threaded rod 700 can be adjusted, so that the heights of multiple clamping blocks 3022 are consistent, thereby making the first concave plate 302 as a whole in a horizontal state, thereby improving the stability of the fixing through hole 3011 on the first mounting platform 300 to the core rod 200.

[0044] In some embodiments, reference Figure 5 , Figure 6 and Figure 8 The split combined mounting platform in the present application also includes: two second mounting platforms 800; specifically, the top surfaces of the two second mounting platforms 800 are each provided with a through hole 301, the two second mounting platforms 800 are fixed together by a first fastener 400 and the two through holes 301 are combined to form a fixed through hole 3011, and the bottom surface of each second mounting platform 800 is fixed to the top surface of the corresponding first mounting platform 300 by a second fastener 801; when the height of the first mounting platform 300 is not enough to meet the installation height of the core rod 200 and the first mounting platform 300 with a larger height is inconvenient to process and occupies a larger space, the installation requirements of the core rod 200 can be met by installing the second mounting platform 800 on the top surface of the first mounting platform 300.

[0045] The second staircase 900 is arranged on one side of one of the second mounting platforms 800 and its bottom end is connected to the top of the first staircase 500, and is used for workers to climb to the top surfaces of the two second mounting platforms 800 and install parts on the peripheral wall of the mandrel 200. The material and shape of the second staircase 900 can be set according to actual needs, and the purpose is to serve as a bridge for workers to reach the second mounting platform 800, thereby improving the convenience of workers to reach the top surface of the second mounting platform 800 from the reference surface.

[0046] In some embodiments, reference Figure 5 and Figure 6 The second mounting platform 800 in the present application includes two second concave plates 303; specifically, the two second concave plates 303 are connected together up and down through the support frame 600, and a mounting plate 304 is provided at the notch of the upper second concave plate 303, and a fixing through hole 3011 is provided on the mounting plate 304. Among them, through the provision of the second mounting platform 800, the split combined mounting platform in the present application can be suitable for the installation of parts on the mandrel 200 with a relatively high height.

[0047] In some embodiments, reference Figure 6 , Figure 7 and Figure 8 The second mounting platform 800 in the present application has multiple layers from top to bottom, and the top surface or bottom surface of each layer of the second mounting platform 800 is connected to the bottom surface of the second mounting platform 800 above it or the top surface of the second mounting platform 800 below it through the second fastener 801. The number of layers of the second mounting platform 800 can be set according to the height of the mandrel 200 that needs to be fixed, so as to effectively fix the mandrel 200 through the fixing through hole 3011 formed by the two through holes 301 thereon and meet the requirement of installing parts at the top of the mandrel 200 with a higher height. The second fastener 801 may include a third fastening bolt and a second nut. The upper and lower second mounting platforms 800 are both provided with a fourth threaded through hole matching the third fastening bolt. The screw end of the third fastening bolt vertically penetrates the fourth threaded through hole on the upper second mounting platform 800 and the fourth threaded through hole on the lower second mounting platform 800 in sequence and a second nut is screwed thereon, thereby achieving fixed connection between the upper and lower second mounting platforms 800 and making installation and disassembly of the second mounting platform 800 more convenient.

[0048] In addition, refer to Figure 6 A guardrail 3042 is provided on the peripheral side of the top surface of the second mounting platform 800 located at the top layer. Since the charging core mold needs to be installed vertically at 90 degrees perpendicular to the ground, specifically, the main core rod is hoisted and vertically installed into the chuck on the ground. After the bottom end of the main core rod is firmly fixed, the staff stands on the mounting platform to install the bottom wing and the top wing of the main core rod in turn. Therefore, when the height of the core rod is relatively high, in order to prevent the staff from accidentally falling from it when standing on the top of the second mounting platform 800 on the top layer to install the parts at the top end of the core rod 200, the safety of the staff's operation process is improved.

[0049] In some embodiments, the upper surface of the second concave plate 303 in the present application is provided with an anti-skid layer. The anti-skid layer may be a patterned plate, the purpose of which is to increase the friction between the sole of the worker's shoe and the second concave plate 303, so that the worker standing on the second concave plate 303 to install the parts at the top of the mandrel 200 is more stable.

[0050] In some embodiments, reference Figure 1 , Figure 2 and Figure 4 The split combined installation platform in the present application also includes a plurality of limiting top plates 1000 for limiting the core rod 200 passing through the fixing through hole 3011. The plurality of limiting top plates 1000 are fixed on the installation plate 304 at equal intervals around the core rod 200 by first fastening bolts 1001. The limiting top plates 1000 may be "L" shaped. The core rod 200 is fixed by a plurality of limiting top plates 1000, so that the contact area between the peripheral wall of the core rod and the plurality of limiting top plates is increased, thereby improving the stability of the core rod. The number of limiting top plates 1000 can be set according to actual needs, so the present application does not specifically limit it here.

[0051] In some embodiments, reference Figure 1 , Figure 2 , Figure 4 and Figure 6 In the present application, a plurality of groups of second threaded through holes 3041 are provided on the mounting plate 304, and the plurality of groups of second threaded through holes 3041 correspond one-to-one to the plurality of limiting top plates 1000, and each group of second threaded through holes 3041 has at least two, in order to improve the stability of the first fastening bolts 1001 fixing the limiting top plates 1000.

[0052] Each limiting top plate 1000 is provided with a strip through hole 1002 along its length direction, and the screw end of the first fastening bolt 1001 sequentially penetrates the strip through hole 1002 and the second threaded through hole 3041 to fix the limiting top plate 1000 on the mounting plate 304. The provision of the strip through hole 1002 enables the limiting top plate 1000 to be used for fixing mandrels 200 of different diameters. In the process of fixing the mandrel 200 through the limiting top plate 1000, one end of the limiting top plate 1000 is abutted against the outer wall of the mandrel 200, and then the screw end of the first fastening bolt 1001 sequentially penetrates the strip through hole 1002 and the second threaded through hole 1002 to fix the limiting top plate 1000 on the mounting plate 304, thereby achieving the fixing of the mandrel 200 by the limiting top plate 1000.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
